Bismuth-based materials in electrocatalytic CO2 reduction (CO2RR) usually face the problem of high overpotential. We first show a covalently modified electrode with Bi nanoparticles encapsulated ultrathin porous organic polymer nanosheets (POPs) amine linkages to effectively reduce overpotential for CO2-to-formate conversion, which exhibits formate Faradaic efficiency (FEHCOO-) 98.5% and partial current density up 148.7 mA cm-2 at -0.85 V comparison that bare bismuth FEHCOO- 85% -1.15 (versus reversible hydrogen electrode). Different from reaction mechanism *CO2•- radicals as intermediate over sites, situ spectroscopic studies functional theory calculations reveal abundant POPs backbone provide chemisorption sites interact enriched molecules form carbamates (*[-NCOO-]) intermediates low barrier 0.064 eV, significantly reduces free energy conversion process formate. Moreover, promote water dissociation subsequent protonation on surface reduced -0.31 eV than 0.11 eV. This work not only delivers new but also offers clean platform investigate influence modification.

Abstract CO 2 reduction reaction (CO RR) has attracted considerable attention as a sustainable approach for carbon capture and conversion. However, the dynamic nature of electrocatalysts under operational conditions, particularly at interface, presents significant challenges understanding mechanisms optimizing catalyst design. In situ/operando characterization techniques are crucial to interfaces RR. This review focuses on various in employed explore interfaces, insights derived from these studies, their implications
