Main group indium materials have been known as promising electrocatalysts for two-electron-involved carbon dioxide reduction to produce formate, which is a key energy vector in many industrial reactions. However, the synthesis of two-dimensional (2D) monometallic nonlayered remains great challenge. Here, we present facile electrochemical strategy transform 2D coordination polymer into elemental nanosheets. In customized flow cell, reconstructed metallic exhibits high Faradaic efficiency (FE) 96.3% formate with maximum partial current density exceeding 360 mA cm-2 and negligible degradation after 140 h operation 1 M KOH solution, outperforming state-of-the-art indium-based electrocatalysts. Moreover, ex situ analysis characterizations demonstrate that enhanced exposure active sites mass/charge transport at CO2 gas-catalyst-electrolyte triple-phase interface restrained electrolyte flooding are contributing producing stabilizing radical anion intermediates, thus leading superior catalytic performance.

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.

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.
