Nano silver oxide-modified activated carbon as a novel catalyst for efficient removal of bacteria and micropollutants in aquatic environment.

ABSTRACT: Heterogeneous Fenton process is a promising water treatment technology for sterilization and degradation of organic pollutants, due to the strong oxidation of hydroxyl radicals (OH˙) generated. However, the low H₂O₂ activation efficiency and the instability of catalyst leading to low OH˙ production restricted development of this technology. Herein, we synthesized a novel porous activated carbon-loaded nano silver oxide (nAg₂O/AC) catalyst to enhance the activation of H₂O₂ for removing bacteria (E. coli) and micropollutants (Tetracycline, TC) from water. In the nAg₂O/AC Fenton system, reductive hydroxyl groups on AC accelerated Ag(i)/Ag cycle through mediated electron transfer, which markedly increased H₂O
