Microenvironment engineering by targeted delivery of Ag nanoparticles for boosting electrocatalytic CO₂ reduction reaction.

ABSTRACT: Creating and maintaining a favorable microenvironment for electrocatalytic CO₂ reduction reaction (eCO₂RR) is challenging due to the vigorous interactions with both gas and electrolyte solution during the electrocatalysis. Herein, to boost the performance of eCO₂RR, a unique synthetic method that deploys the in situ reduction of precoated precursors is developed to produce activated Ag nanoparticles (NPs) within the gas diffusion layer (GDL), where the thus-obtained Ag NPs-Skeleton can block direct contact between the active Ag sites and electrolyte. Specifically, compared to the conventional surface loading mode in the acidic media, our freestanding and binder free electrode can achieve obvious higher CO selectivity of 94%, CO production rate of 23.3 mol g
