ACS Catalysis, Journal Year: 2022, Volume and Issue: 12(15), P. 9735 - 9752

Published: July 27, 2022

Electrochemical reduction of CO2 to high-value hydrocarbons and oxygenates is an attractive technique store intermittent renewable energy. Diverse catalysts are capable catalyzing the CO conversion, while further occurs almost exclusively on Cu. Monocomponent Cu suffer from high overpotential low Faradaic efficiency oxygenates. Combining conversion Au, Ag, single-atom catalysts, etc., with a promising strategy achieve selectivity formation rate highly reduced products. Numerous tandem have been developed based this idea, mass transport intermediate CO-formation catalyst key factor that needs be considered in design catalysts. Rational analysis different modes reported designs needed for development reduction. In review, we elucidate how spatial distribution determines mode consequently affects utilization intermediate. We also discuss challenges perspectives understanding interaction between improving their catalytic performance

Published: March 12, 2022

Abstract Photocatalytic conversion of CO 2 to high-value products plays a crucial role in the global pursuit carbon–neutral economy. Junction photocatalysts, such as isotype heterojunctions, offer an ideal paradigm navigate photocatalytic reduction reaction (CRR). Herein, we elucidate behaviors heterojunctions toward CRR over representative photocatalyst, g-C 3 N 4 . Impressively, possess significantly higher efficiency for spatial separation and transfer photogenerated carriers than single components. Along with intrinsically outstanding stability, exhibit exceptional stable activity photoreduction CO. More importantly, by combining quantitative situ technique first-principles modeling, that enhanced photoinduced charge dynamics promotes production key intermediates thus whole kinetics.
