Abstract The present energy crisis and environmental challenges may be efficiently resolved by converting carbon dioxide (CO 2 ) into various useful products. development of more effective catalysts has been the main focus current research on photocatalytic CO reduction. Due to their high atomic efficiency superior catalytic activity, single‐atom (SACs) have attracted considerable interest in conversion. This review discusses developments, obstacles, potential SACs for And further, principle work compared analyzed effects support materials active site types reduction performance. believes that sharing these some inspiration rational design stable based can provided.

The electrochemical CO2 reduction reaction (CO2RR) is an important application that can considerably mitigate environmental and energy crises. However, the slow proton-coupled electron transfer process continues to limit overall catalytic performance. Fine-tuning microenvironment by accurately constructing local structure of catalysts provides a novel approach enhancing kinetics. Here, cubic-phase α-MoC1-x nanoparticles were incorporated into carbon matrix coupled with cobalt phthalocyanine molecules (α-MoC1-x-CoPc@C) for co-reduction H2O, achieving impressive Faradaic efficiency CO close 100%. Through combination in-situ spectroscopies, measurements, theoretical simulations, it demonstrated CoPc optimized configuration serve as active centers H2O activation reduction, respectively. interfacial water rearranged, forming dense hydrogen bond network on catalyst surface. This at electrode-electrolyte interface synergistically enhanced dissociation, accelerated proton transfer, improved performance CO2RR.

Abstract Improving proton transfer is vital for electrocatalysis with porous materials. Although several strategies are reported to assist in channels, few studies dedicated improving at the local environments of active sites Herein, we report on new Co‐corrole‐based organic polymers (POPs) improved electrocatalytic oxygen reduction reaction (ORR) and evolution (OER). By tuning pore sizes installing relays Co corrole sites, designed synthesized POP‐2‐OH both channels sites. This POP shows remarkable activity ORR E 1/2 =0.91 V vs RHE OER η 10 =255 mV. Therefore, this work significant present a strategy improve site materials highlight key role such structural functionalization boosting electrocatalysis.

Abstract Carbon dioxide (CO₂) electroreduction in aqueous electrolytes is a complex electrochemical process that involves the transfer of multiple electrons and protons, resulting various reaction pathways products. A critical step this dissociation water, which provides protons significantly affects * CO hydrogenation pathways, as well hydrogen evolution. In study, copper‐based catalysts are modified through situ polymerization dopamine to create intimate polymer coatings regulate surface water process. This modification leads notable shift product distribution CO₂ electroreduction, from predominantly multicarbon compounds methane, accompanied with ratio CH 4 /C 2+ changing 0.5 1.8. At high current densities, polymer‐modified catalyst exhibited stable methane production Faradaic efficiency up 60%. Kinetic isotopic effects, infrared spectroscopy, theoretical calculations revealed polydopamine plays crucial role altering selectivity by regulating hydrolysis. work signifies importance polymer‐regulated hydrolysis steer 2 reduction pathways.
