摘要 : The abuse of antibiotics poses a significant threat to both human health and the ecosystem, while the rapid screening of multiple antibiotics remains a challenge. We report the design of a dual-site peroxidase (POD)-mimic nanozyme comprising self-assembled hemin molecules and Cu 2 + on graphdiyne (GDY) for screening of multiple antibiotics assisted with machine learning (ML). Cu ions can bond with π bonds and carbonyl groups on the surface of GDY, thereby enabling strong interface of hemin and GDY for an enhanced generation of hydroxyl radicals ( . OH). GDY/Hemin/Cu exhibits POD-like activity in wide pH conditions and temperatures ranging from 20 to 70 °C. With the assistance of ML, GDY/Hemin/Cu-based colorimetric sensor arrays demonstrate fast and accurate identification of multiple antibiotics including kanamycin, norfloxacin, ampicillin sodium, catechol and isoniazid. Theoretical calculation confirms that strong binding affinity enables specificity of the GDY/Hemin/Cu towards antibiotics. By employing support vector machine algorithm to assess antibiotic content, a high detection accuracy of 97.5 % is achieved across 40 honey samples, underscoring the potential practical applications in screening of multiple antibiotics.

摘要 : Rattan is a multi-purpose plant resource in the tropical forest treasure house. With its good technological characteristics, it has become an excellent material for the preparation of industry. The original rattan is an important forest product second only to wood and bamboo. The annual output of the original rattan is millions of tons, which plays an important role in regional economic and social development. Rattan is mainly used for the manufacture of furniture, crafts and accessories, of which >95 % of the palm rattan is used for the production of furniture. Based on the physical and chemical structure of rattan, this paper discusses the common modification methods such as chemical treatment, bleaching and resin impregnation in recent years in view of the defects of rattan itself. The high value-added materials developed by using rattan as the base material in recent years were further reviewed, including rattan-based porous carbon materials, rattan-plastic composites, rattan-based ceramics, rattan-fiber-based materials and rattan-stem-based composites, aiming to broaden their application fields and promote the development and utilization of rattan resources and industrial development.

摘要 : The design of self-supporting structure is particularly important to improve the stability and electrochemical performance of hydrogen evolution reaction electrode. Here, a facile strategy for building novel ultra-stable 0D-2D-3D integrated self-supporting electrode with high conductivity, sufficient diffusion channels and large reactive surface area was proposed. In the heterostructure, 2D Ti 3 C 2 T x flakes in-situ synthesized on 3D network porous Ti 3 AlC 2 surface which provides the multiple reactive surface areas and aggregation resistance to facilitating 0D ultrafine Pt nanoparticles uniform anchorage. Combined with structural characterization and first-principles calculations revealed that, the highly dispersed ultrafine Pt synergistically coupling strong metal-support interactions creates a unique multifunctional catalytic interface with high stability and atomic utilization efficiency of Pt to promote the HER in acidic and seawater. The resultant self-supporting electrode (support 0.48 wt% Pt) exhibits much superior activity to 10 % commercial Pt/C (loaded on foam nickel) in 0.5 M H 2 SO 4 (55 mV@10 mA cm −2 ) and simulate seawater (196 mV@10 mA cm −2 ) while reducing the Pt usage by 15 times. Meanwhile, the electrode also illustrates outstanding stability under high current densities (100 h@100 mA cm −2 ). This study provides a new design idea for developing integrated self-supporting catalytic electrodes to meet the durability of hydrogen evolution reaction applications in harsh environments.

摘要 : Microbial Fuel Cells (MFCs) have garnered significant research attention as promising candidates for efficient and eco-friendly energy storage solutions. However, the persistent obstacle of limited electron transfer efficiency continues to hinder their widespread adoption. This study innovatively tackles the challenge of low electron transfer efficiency in MFCs by copolymerizing a conjugated polymer (PDA) with a photocatalytic material (TiO 2 ) onto Shewanella putrefaciens CN32 to create a hybrid microorganism. These hybrids, particularly when utilized as catalysts within MFCs under light illumination, significantly boosted electron transfer rates. Remarkably, the hybrid microorganism demonstrated an impressive current density of 1.07 mA/cm 2 in darkness, which soared to 5.657 mA/cm 2 under illumination. This microorganism exemplifies the synergistic interplay between the PDA and TiO 2, where the PDA serves as an electron accumulator, while TiO 2 converts photons into valuable energy, ultimately enhancing the overall electrochemical performance of the MFCs. This work not only underscores the potential of integrating conjugated polymers and photocatalytic technology within bioelectrochemical systems but also expands the avenues for the development of more efficient and sustainable MFCs.

摘要 : Atomically dispersed tungsten-nitrogen-carbon with W−N 4 sites acts as a highly efficient catalyst for oxygen reactions. However, the symmetrical charge distribution of W−N 4 sites results in strong binding with oxygen-containing intermediates, leading to unsatisfactory catalytic activities. Here, an axially coordinated sulfur (S) atom is integrated into the atomically dispersed W−N 4 site and anchored onto multi-walled carbon nanotubes (S 1 −W 1 N 4 −MWCNTs) for oxygen reduction/oxygen evolution reactions (ORR/OER). The axial S atom, with significantly different electronegativity and outer electronic structure compared to nitrogen atom, induces localized charge redistribution around W−N 4 site. This change optimizes the adsorption/desorption capabilities of oxygen-containing intermediates on W−N 4 site, thereby enhancing the overall oxygen reaction activities. The S 1 −W 1 N 4 −MWCNTs demonstrates excellent ORR/OER activity with the half-wave potential of 0.916 V for ORR and the potential of 1.644 V (at 10 mA cm −2 ) for OER. At −20 °C, S 1 −W 1 N 4 −MWCNTs-based zinc-air batteries demonstrate increased specific capacity and an extended charging-discharging cycle life of 420 h, surpassing performance at room temperature. Regulating the charge distribution of W−N 4 sites with axial S atoms provides an effective strategy to boost the oxygen reaction activities of tungsten-nitrogen-carbon catalysts.

摘要 : Porous carbon has been widely used in aqueous capacitors due to its wide source, high stability, and controllable preparation. However, the two-step preparation strategy of carbonization and activation with complex operation and serious energy consumption severely limits its further application. In this paper, resorcinol/urea-furfural resin was successfully prepared by using cleaner and greener furfural as raw material and co-crosslinking with resorcinol and urea under the action of catalyst. It is noteworthy that during the curing process, KOH is uniformly anchored inside the resin, so the system only needs one-step high-temperature pyrolysis to obtain a N-doped ant-nest-like three-dimensional interconnected porous carbon material. Consequently, the porous carbon exhibited an impressive specific capacitance of 283F g −1 . The assembled symmetrical device shows a capacitance retention of 92 % after 50 000 cycles, showing excellent cycle stability. In addition, the assembled zinc ion hybrid capacitor exhibits a capacitance of 138 mAh g −1 and an energy density of 111 Wh kg −1 . The one-step carbonization-doping-activation strategy of this bottom-up in-situ anchoring activator will provide further insights into the hierarchical pore structure design of porous carbon and facilitate the simple and efficient preparation of carbon materials.

摘要 : Vanadium-based oxides have good application prospects in aqueous zinc ion batteries (AZIBs) due to their structures suitable for zinc ion extraction and intercalation. However, their poor conductivity limits their further development. The d-band center plays a key role in promoting adsorption of ions, which promotes the development of electrode materials. Here, a series of MoV 2 O 8 compounds with oxygen defect (O d -MoV 2 O 8 ) were synthesized by a simple hydrothermal process and a subsequent vacuum calcination process through strict control of the deoxidation time. Theoretical calculations reveal that the abundant oxygen vacancies in MoV 2 O 8 effectively regulate the d-band center of the zinc ion adsorption site. This precise control of the d-band center enhances the zinc ion adsorption energy of MoV 2 O 8, lowers the migration energy barrier for zinc ions, and ultimately significantly boosts zinc storage performance. The specific capacity is as high as 282.4 mAh/g after 100 cycles at 0.1 A/g, and it also shows excellent performance and outstanding cycle life. In addition, the maximum energy density of O d -MVO-0.5 (MoV 2 O 8 sample deoxidized for 0.5 h) is 343.3 Wh kg −1 . Importantly, the mechanism of Zn 2+ storage in O d -MoV 2 O 8 was revealed by the combination of in situ and ex situ characterization techniques.

摘要 : Two-dimensional (2D) Pd-based nanostructures with a high active surface area and a large number of active sites are commonly used in alcohol oxidation research, whereas the less explored ring structure made of nanosheets with large pores is of interest. In this study, we detail the fabrication of PdCu nanorings (NRs) featuring hollow interiors and low coordinated sites using a straightforward solvothermal approach. Due to increased exposure of active sites and the synergistic effects of bimetallics, the PdCu NRs exhibited superior catalytic performance in both the ethanol oxidation reaction (EOR) and the ethylene glycol oxidation reaction (EGOR). The mass activities of PdCu NRs for EOR and EGOR were measured at 7.05 A/mg and 8.12 A/mg, respectively, surpassing those of commercial Pd/C. Furthermore, the PdCu NRs demonstrated enhanced catalytic stability, maintaining higher mass activity levels compared to other catalysts during stability testing. This research offers valuable insights for the development of efficient catalysts for alcohol oxidation.

摘要 : While great efforts have been made to improve the electrocatalytic activity of existing materials toward hydrogen evolution reaction (HER), it is also importance for searching new type of nonprecious HER catalysts to realize the practical hydrogen evolution. Herein, we firstly report nanocrystalline transition metal tetraborides (TMB 4, TM=W and Mo) as an efficient HER electrocatalyst has been synthesized by a single-step solid-state reaction. The optimized nanocrystalline WB 4 exhibits an overpotential as low as 172 mV at 10 mA/cm 2 and small Tafel slope of 63 mV/dec in 0.5 M H 2 SO 4 . Moreover, the nanocrystalline WB 4 outperforms the commercial Pt/C at high current density region, confirming potential applications in industrially electrochemical water splitting. Theoretical study reveals that high intrinsic HER activity of WB 4 is originated from its large work function that contributes to the weak hydrogen-adsorption energy. Therefore, this work provides new insights for development of robust nanocrystalline electrocatalysts for efficient HER.

摘要 : Cellulose, as a natural polymer material, has attracted considerable attention in the field of water treatment due to its reproducibility, versatility, low cost and biodegradability. Cellulose-MOFs (CelloMOFs) are prepared by combining cellulose with metal–organic frameworks (MOFs). This combination could modulate the microstructure and macroform of composites, enhancing their properties, such as adsorption capacity, pollutant degradation, mechanical strength, and pore structure. It also broadens their application potential in water treatment. CelloMOFs have been demonstrated to possess effective adsorption capabilities to removal of a range of pollutants, including heavy metal ions, dyes, pharmaceuticals, and oil from wastewater. Additionally, CelloMOFs can also be used as an efficient catalysts and membrane materials for the degradation of organic pollutants, seawater desalination and dye separation. Furthermore, CelloMOFs can be prepared into sensors for the detection of pollutants. This review presents an overview of the synthesis methods employed in the preparation of cellulose-MOFs and their applications in water treatment. The modification of cellulose, the synthesis methods of CelloMOFs, and the applications of adsorption, catalysis, membrane separation, and sensing were discussed. Then, the problems and improvement methods of the application process are analyzed. Finally, the challenges and future prospects of cellulose-MOFs are discussed.
