Description
Summary:We improve the photocatalytic effect of Ag 2 S under visible light by using fullerene modified with Ag 2 S nanoparticles. Surface areas and pore volumes of the Ag 2 S-fullerene samples showed catastrophic decreases due to the deposition of Ag 2 S. 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 Ag 2 S and fullerene nanoparticles, the photocatalytic effect of the fullerene modified with Ag 2 S composites is increased significantly due to the synergetic effect between the fullerene and the Ag 2 S nanoparticles. We improve the photocatalytic effect of Ag 2 S under visible light by using fullerene modified with Ag 2 S nanoparticles.
