Electrochemical urea oxidation reaction(UOR) is a promising alternative to oxygen evolution reaction(OER) for realizing energy-saving hydrogen production. Developing efficient electrocatalysts for UOR becomes a central challenge. Recently, amorphous materials have been extensively used as UOR catalysts because of their numerous defective sites and flexible electronic properties. In this review, recent advancements in the development of amorphous UOR electrocatalysts are analyzed. The UOR mechanism is discussed, and the design of amorphous catalysts is then analyzed. The main catalyst design strategies are illustrated, including nanostructure control,heteroatom doping, composition regulation, and heterostructure construction. Also, electrocatalysts' structureperformance correlation is interpreted. Perspectives in this field are proposed for guiding future studies on the development of high-performance amorphous catalysts towards energy sustainability.

Electro-upcycling of plastic waste into value-added chemicals/fuels is an attractive and sustainable way for plastic waste management.Recently,electrocatalytically converting polyethylene terephthalate(PET)into formate and hydrogen has aroused great interest,while developing low-cost catalysts with high efficiency and selectivity for the central ethylene glycol(PET monomer)oxidation reaction(EGOR)remains a challenge.Herein,a high-performance nickel sulfide catalyst for plastic waste electro-upcycling is designed by a cobalt and chloride co-doping strategy.Benefiting from the interconnected ultrathin nanosheet architecture,dual dopants induced upshifting d band centre and facilitated in situ structural reconstruction,the Co and Cl co-doped ni_(3)S_(2)(Co,Cl-niS)outperforms the singledoped and undoped analogues for EGOR.The self-evolved sulfide@oxyhydroxide heterostructure catalyzes EG-to-formate conversion with high Faradic efficiency(>92%)and selectivity(>91%)at high current densities(>400 mA cm^(−2)).Besides producing formate,the bifunctional Co,Cl-niS-assisted PET hydrolysate electrolyzer can achieve a high hydrogen production rate of 50.26 mmol h^(−1)in 2 M KOH,at 1.7 V.This study not only demonstrates a dual-doping strategy to engineer cost-effective bifunctional catalysts for electrochemical conversion processes,but also provides a green and sustainable way for plastic waste upcycling and simultaneous energy-saving hydrogen production.

Manipulating the structure self-reconstruction of transition metal sulfide-based(pre)catalysts during the oxygen evolution reaction(OER) process is of great interest for developing cost-effective OER catalysts,which remains a central challenge. Here we realize a deep structure self-reconstruction of natural chalcopyrite to unlock its OER performance via mechanochemical activation. Compared with the manually milled counterpart(CuFeS_(2)-HM), the mechanically milled catalyst(CuFeS_(2)-BM) with a reduced crystallinity exhibits a 7.11 times higher OER activity at 1.53 V vs. RHE. In addition, the CuFeS_(2)-BM requires a low overpotential of 243 mV for generating 10 mA cm^(-2) and exhibits good stability over 24 h. Further investigations suggest that the excellent OER performance of CuFeS_(2)-BM mainly originates from the decreased crystallinity induced the in situ deep structure self-reconstruction of the originally sulfides into the electroactive and stable metal(oxy)hydroxide phase(e.g., a-Fe OOH) via S etching under OER conditions. This study demonstrates that regulating the crystallinity of catalysts is a promising design strategy for developing highly efficient OER catalysts via managing the structure self-reconstruction process, which can be further extended to the design of efficient catalysts for other advanced energy conversion devices. In addition, this study unveils the great potentials of engineering abundant natural minerals as cost-effective catalysts for diverse applications.

Artificial ammonia synthesis using solar energy is of great significance as it can help narrow the gap to the zero-net emission target.However,the current photocatalytic activity is generally too low for mass production.Herein,we report a novel bismuth bromide oxide(BiOBr)-Tetracyanoquinodimethane(TCNQ)photocatalyst prepared via a facile self-assembly method.Due to the well-match band structure of TCNQ and Bi OBr,the separation and transfer of photogenerated electron-hole pairs were significantly boosted.More importantly,the abundant delocalizedπelectrons of TCNQ,and the electron-withdrawing property of TNCQ made electrons efficiently accumulated on the catalysts,which can strengthen the adsorption and cleavage of nitrogen molecules.As a result,the photocatalytic activity increased significantly.The highest ammonia yield of the optimized sample reached 2.617 mg/(h gcat),which was 5.6-fold as that of pristine BiOBr and higher than the reported BiOBr-based photocatalysts.The isotope labeled^(15)N_(2)was used to confirm that the ammonia is formed form the fixation of N_(2).Meanwhile,the sample also had good stability.After 4-time usage,the photocatalysts still had about 81.8%as the fresh sample.The results of this work provide a new way for optimizing the electronic structure of photocatalysts to achieve highly efficient photochemical N_(2) reduction.

Perturbation of clopyralid on bio-denitrification and nitrite accumulation:Long-term performance and biological mechanism

作者： Suyun Sun Ya-Nan Hou Wei Wei Hafiz Muhammad Adeel Sharif Cong Huang bing-jie ni Haibo Li Yuanyuan Song Caicai Lu Yi Han Jianbo Guo Tianjin Key Laboratory of Aquatic Science and Technology School of Environmental and Municipal EngineeringTianjin Chengjian UniversityTianjin300384China National Technology Innovation Center of Synthetic Biology Tianjin Institute of Industrial BiotechnologyChinese Academy of SciencesTianjin300308China Centre for Technology in Water and Wastewater School of Civil and Environmental EngineeringUniversity of Technology SydneySydneyNSW2007Australia College of Chemistry and Environmental Engineering Shenzhen UniversityShenzhen518060China

The contaminant of herbicide clopyralid(3,6-dichloro-2-pyridine-carboxylic acid,CLP)poses a potential threat to the ecological system.However,there is a general lack of research devoted to the perturbation of CLP to the bio-denitrification process,and its biological response mechanism remains unclear.Herein,long-term exposure to CLP was systematically investigated to explore its influences on denitrification performance and dynamic microbial responses.Results showed that low-concentration of CLP(nitrite accumulation initially,while higher concentrations(35e60 mg/L)of CLP had no further effect after long-term acclimation.The mechanistic study demonstrated that CLP reduced nitrite reductase(niR)activity and inhibited metabolic activity(carbon metabolism and nitrogen metabolism)by causing oxidative stress and membrane damage,resulting in nitrite accumulation.However,after more than 80 days of acclimation,almost no nitrite accumulation was found at 60 mg/L CLP.It was proposed that the secretion of extracellular polymeric substances(EPS)increased from 75.03 mg/g VSS at 15 mg/L CLP to 109.97 mg/g VSS at 60 mg/L CLP,which strengthened the protection of microbial cells and improved niR activity and metabolic activities.Additionally,the biodiversity and richness of the microbial community experienced a U-shaped process.The relative abundance of denitrification-and carbon metabolism-associated microorganisms decreased initially and then recovered with the enrichment of microorganisms related to the secretion of EPS and N-acyl-homoserine lactones(AHLs).These microorganisms protected microbe from toxic substances and regulated their interactions among interand intra-species.This study revealed the biological response mechanism of denitrification after successive exposure to CLP and provided proper guidance for analyzing and treating herbicide-containing wastewater.
