Boosting thermo-photocatalytic CO2 conversion activity by using photosynthesis-inspired electron-proton-transfer mediators

Natural photosynthesis proceeded by sequential water splitting and CO 2 reduction reactions is an efficient strategy for CO 2 conversion. Here, mimicking photosynthesis to boost CO 2 -to-CO conversion is achieved by using plasmonic Bi as an electron-proton-transfer mediator. Electroreduction of H 2 O with a Bi electrode simultaneously produces O 2 and hydrogen-stored Bi (Bi-H x ). The obtained Bi-H x is subsequently used to generate...
