WebThe modification of rGO endowed the photocatalyst with improved visible-light absorption, stronger reductive ability, and faster separation rate of photoinduced carriers. Moreover, the covalent C–O–C bond formed in the two components facilitates the directional transfer of photoinduced electrons. A low-cost and robust photocatalyst for ... WebPhotocatalysis is an ecofriendly technique that emerged as a promising alternative for the degradation of many organic pollutants. The weaknesses of the present photocatalytic system which limit their industrial applications include low-usage of visible light, fast charge recombination, and low migration ability of the photo-generated electrons and holes.
