摘要

Reactive oxygen species (ROS) can be produced by interactions between sunlight and light-absorbing substance in natural water environment and can completely destroy various organic pollutants in wastewaters. In this study, a novel Ag2Se-C-70 heterojunction photocatalysts were successfully prepared. Surface area and pore volumes of the Ag2Se-C-70 samples showed decrease due to deposition of Ag2Se. The generations of ROS were detected through the oxidation reaction from DPCI to DPCO. The photocurrent density and the PGO effect increase in the case with the modified C-70. The PGO effect of the C-70 modified with Ag2Se composites is increased significantly due to the synergetic effect between the C-70 and the Ag2Se nanoparticles.
