Abstract
AbstractIn this study, CdS/g‐C3N4/Vermiculite composites were prepared by hydrothermal and calcinated with expanded‐ vermiculite as host photocatalysis. Compared with other reference samples, the received CS/CN/VMT composite material has significantly enhanced photocatalytic activity on rhodamine B and methylene blue. The significantly enhanced catalytic efficiency is a benefit originating from the large specific surface area of vermiculite and the excellent electron transport efficiency between g‐C3N4 and CdS. Moreover, the degradation rate of the catalyst can still reach 96 % after being repeated four times, indicating that the composite catalyst has facilitated stability and recyclability. Particle capture experiments and ESR studies show that the .O2− is the primary active substance of CS/CN/VMT, and a possible photocatalytic degradation path has been proposed.
