外文摘要：Solar-driven CO2 conversion into hydrocarbon fuels is a sustainable approach to synchronously alleviating the energy crisis and achieving net CO2 emissions.However,the dependence of the conversion process on solar illumination hinders its practical application due to the intermittent availability of sunlight at night and on cloudy or rainy days.Here,we report a model material of Pt-loaded hexagonal tungsten trioxide(Pt/h-WO3)for decoupling light and dark reaction processes,demonstrating the sustainable CO2 conversion under dark conditions for the first time.In such a material system,hydrogen atoms can be produced by photocatalytic water splitting under solar illumination,stored together with electrons in the h-WO3 through the transition of W6+to W5+and spontaneously released to trigger catalytic CO2 reduction under dark conditions.Furthermore,we demonstrate using natural light that CH4 production can persist at night and on rainy days,proving the accomplishment of all-weather CO2 conversion via a sustainable way.
