Abstract CO 2 reduction reaction (CO RR), as a promising strategy for storing renewable energy and promoting carbon resource recycling, is critical industrial development. Previous reports have extensively explored catalyst‐electrolyte microenvironmental modulation to elucidate coupling mechanisms enhance catalytic conversion multicarbon products. Currently, most reviews mainly focus on the impact of microenvironment in low‐current systems mechanism exploration performance optimization, yet few them can integrate macroscopic applications with microscopic investigations explore relevance between development optimization. To address gap, this review focuses summarizing challenges advancements high‐current devices. By introducing models different scales sequentially, connection device clarified. Then, various invalidation effective solutions are summarized intuitively expound stability. Meanwhile, an intuitive measure rationality modulation, evaluation methods should be refined, which also covered further detail below. Finally, more valuable challenging prospects discussed guiding transformation RR.

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.

Electrocatalytic carbon dioxide reduction reaction (CO2RR) toward value-added chemicals/fuels has offered a sustainable strategy to achieve carbon-neutral energy cycle. However, it remains great challenge controllably and precisely regulate the coordination environment of active sites in catalysts for efficient generation targeted products, especially multicarbon (C2+) products. Herein we report engineering metal centers polymers electroreduction CO2 C2+ products under neutral conditions. Significantly, Cu polymer with Cu–N2S2 configuration (Cu–N–S) demonstrates superior Faradaic efficiencies 61.2% 82.2% ethylene respectively, compared selective formic acid on an analogous Cu–I2S2 mode (Cu–I–S). In situ studies reveal balanced formation atop bridge *CO intermediates Cu–N–S, promoting C–C coupling production. Theoretical calculations suggest that can induce electronic modulations sites, where d-band center is upshifted Cu–N–S stronger selectivity Consequently, displays trend while Cu–I–S favors due suppression couplings pathways large barriers.

Electrocatalytic carbon dioxide (CO2) reduction reaction (CO2RR) has offered a sustainable approach in converting an anthropogenic CO2 source to chemicals and fuels promote neutral. However, it remains challenging prepare high-performance catalysts for efficient selective electroreduction, especially toward the high-vaule multicarbon products. Here we report facile synthesis of four kinds nearly monodispersed CuTrz (HTrz = 1H,1,2,4-triazole) metal–organic framework (MOF) nanostructures with different sizes by controlling kinetics. Significantly, small demonstrate much superior CO2RR performance over large counterparts production neutral electrolytes, optimized Faradaic efficiency 55.4% 81.8% ethylene products, respectively. Detailed structural characterizations reveal that are polycrystalline rich grain boundaries, while ones single crystalline. This work highlights importance simultaneous defect size control MOFs boosting their production.

Abstract The electrochemical carbon dioxide reduction reaction (CO 2 RR) is a promising approach for reducing atmospheric ) emissions, allowing harmful CO to be converted into more valuable carbon‐based products. On one hand, single (C 1 products have been obtained with high efficiency and show great promise industrial capture. However, multi‐carbon 2+ possess market value demonstrated significant as potential RR. Due RR's multiple pathways similar equilibrium potentials, the extended mechanisms necessary form C continue reduce overall selectivity of ‐to‐C electroconversion. Meanwhile, RR whole faces many challenges relating system optimization, owing an intolerance low surface pH, systemic stability utilization issues, competing side in H evolution (HER). Ethylene 4 remains incredibly within chemical industry; however, current established method producing ethylene (steam cracking) contributes emission atmosphere. Thus, strategies significantly increase this technology are essential. This review will discuss vital factors influencing forming summarize recent advancements electrosynthesis.
