Abstract

We improve the photocatalytic effect of Ag2S under visible light by using fullerene modified with Ag2S nanoparticles. Surface areas and pore volumes of the Ag2S–fullerene samples showed catastrophic decreases due to the deposition of Ag2S. The generation of reactive oxygen species was detected through the oxidation reaction from 1,5-diphenyl carbazide (DPCI) to 1,5-diphenyl carbazone (DPCO). It is found that the photocurrent density and the photocatalytic effect increase in the case with the modified fullerene. In comparison with the separate effects of Ag2S and fullerene nanoparticles, the photocatalytic effect of the fullerene modified with Ag2S composites is increased significantly due to the synergetic effect between the fullerene and the Ag2S nanoparticles.
