Abstract Electrocatalytic carbon dioxide reduction into high‐value chemicals is one of the important solutions to greenhouse effect and energy crisis. However, slow kinetic process eight electrons requires development efficient catalysts improve yields. Single atom (SACs) with high activity selectivity have become an emerging research frontier in field heterogeneous catalysis. Herein, a catalyst comprised Cu single atoms loaded on substrate (Cu‐NC) developed for highly selective electrocatalytic CO 2 methane (CH 4 ). The optimal (Cu‐NC‐1‐4) exhibits faradaic efficiency (FE) over 50 % CH within wide potential window from −1.3 V −1.8 ( vs . RHE) highest FE up 67.22 at −1.6 RHE). Meanwhile, product among all products reaches 93.00 %, decay can be negligible via 70‐hour‐stability‐test. existence atomic dispersed Cu−N 3 sites was verified by high‐angle annular dark scanning transmission electron microscopy (HAADF‐STEM) X‐ray absorption near edge structure (XANES). Density functional theory (DFT) calculations show that effective adsorption key intermediate *CO prompts generation

The electrocatalysis of nitrate to value-added ammonia is an important strategy address the increasingly pressing problem pollution. Nonetheless, this remains a challenging topic within field catalysis. Iron-based materials are considered promising catalysts for reduction NH3, but they prone agglomeration, with low yields and Faraday efficiencies. In study, Fe3O4 nanoparticles were anchored biomass carbon (BC) through in situ annealing strategy, which can utilize reducing properties BC convert Fe3+ ions. These findings indicate that by modulating temperature BC, ratio Fe2+ on catalyst surface be adjusted, thereby increasing active sites available promoting reduction. Transient photovoltage spectroscopy also indicated introduction contributed increase electron transfer rate. efficiency Fe3O4/BC-700 NH3 presence 100 mM NO3– at −0.5 V vs RHE was 91.10% (±2.36) yield rate 4274.25 (±110.09) mmol gcat–1 h–1. results pave way sustainable ammonium synthesis using low-cost environmentally friendly improved catalytic adjusting structure interface behavior.

Electrocatalytic nitrate reduction enables the recovery of from water under mild conditions and generates ammonia for nitrogen fertilizer feedstock in an economical green means. In this paper, Co/biomass carbon (Co/BC) composite catalysts were prepared by co-carbonization straw metal–organic framework material ZIF-67 electrocatalytic using hydrothermal annealing methods. The structure disperses catalyst components well provides a wider specific surface area, which is conducive to adsorption provision more reactive active sites. introduction biomass additionally enhances electrical conductivity facilitates electron transport. After electrochemical testing, Co/BC-100 exhibited best performance ammonia, with yield 3588.92 mmol gcat.−1 h−1 faradaic efficiency 97.01% at −0.5 V vs. RHE potential. This study promising approach construction other efficient cobalt-based electrocatalysts.
