• significant findings, there have been few studies focused on the improvement of the visible light absorption of g-C3N4/rGO hybrid materials [28][29][30][31] and g-C3N4 QDs, and their CO2 photoreduction ability has not yet been reported. Hence, in our present study, metal-free hybrid catalysts consisting of
