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.

Abstract Zinc‐iodine batteries (Zn‐I2) are extremely attractive as the safe and cost‐effective scalable energy storage system in stationary applications. However, inefficient redox kinetics “shuttling effect” of iodine species result unsatisfactory efficiency short cycle life, hindering their commercialization. In this work, Ni single atoms highly dispersed on carbon fibers is designed synthesized anchoring sites dual catalysts for Zn‐I2 batteries, successfully inhibit shuttling boost reaction kinetics. Theoretical calculations indicate that reinforced d‐p orbital hybridization charge interaction between single‐atoms effectively enhance confinement species. also accelerate conversion reactions with tailored bonding structure I─I bonds reduced barrier Consequently, high‐rate performance (180 mAh g −1 at 3 A ), cycling stability (capacity retention 74% after 5900 cycles) high (90% ) achieved. The work provides an effective strategy development hosts catalytic activity batteries.
