As an important part of carbon neutralization, dioxide electroreduction reaction (CO2RR) can convert CO2 into high value-added chemicals and fuels to realize the recycling resources solve problem environmental pollution. Therefore, exploring element species surface structure catalyst plays a central role in improving performance catalyst, enhancing conversion efficiency forming C1 C2+ products. Here, we summarize recent progress selective regulation CO2RR products by different elements. In particular, emphasize structure-property relationship microenvironment metal center substrate, heteroatom doping, hydrogen bond network metal-free polymer, construction heterogeneous catalytic system. At same time, advances for identification active sites mechanistic studies on process reducing are reviewed, as well comprehensive review final Finally, outline inevitable challenges faced present our own recommendations aimed at contributing resource utilization.

Abstract It is significant to develop catalysts with high catalytic activity and durability improve the electrochemical performances of lithium‐oxygen batteries (LOBs). While electronic metal‐support interaction (EMSI) between metal atoms support has shown great potential in field. Hence, effectively performance LOBs, atomically dispersed Fe modified RuO 2 nanoparticles are designed be loaded on hierarchical porous carbon shells (Fe SA ‐RuO /HPCS) based EMSI criterion. revealed that Ru‐O‐Fe 1 structure formed surrounding Ru sites through electron interaction, this could act as ultra‐high driving force center oxygen reduction/evolution reaction (ORR/OER). Specifically, enhances kinetics ORR a certain extent, optimizes morphology discharge products by reducing adsorption energy catalyst for O LiO ; while during OER process, not only greatly OER, but also catalyzes efficient decomposition Li favorable transfer active products. LOBs FeSA‐RuO /HPCS cathodes show an ultra‐low over‐potential, capacity superior durability.

With the increasingly serious greenhouse effect, electrochemical carbon dioxide reduction reaction (CO2RR) has garnered widespread attention as it is capable of leveraging renewable energy to convert CO2 into value-added chemicals and fuels. However, performance CO2RR can hardly meet expectations because diverse intermediates complicated processes, necessitating exploitation highly efficient catalysts. In recent years, with advanced characterization technologies theoretical simulations, exploration catalytic mechanisms gradually deepened electronic structure catalysts their interactions intermediates, which serve a bridge facilitate deeper comprehension structure-performance relationships. Transition metal-based (TMCs), extensively applied in CO2RR, demonstrate substantial potential for further modulation, given abundance d electrons. Herein, we discuss representative feasible strategies modulate catalysts, including doping, vacancy, alloying, heterostructure, strain, phase engineering. These approaches profoundly alter inherent properties TMCs interaction thereby greatly affecting rate pathway CO2RR. It believed that rational design modulation fundamentally provide viable directions development toward conversion many other small molecules.
