摘　　要：Solar-driven CO_(2)conversion into hydrocarbon fuels is a sustainable approach to synchronously alleviating the energy crisis and achieving net CO_(2)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 CO_(2)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-WO_(3)through the transition of W^(6+)to W^(5+)and spontaneously released to trigger catalytic CO_(2)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 CO_(2)conversion via a sustainable way.
