Abstract
Ag/AgCl/activated carbon (AC) plasmonic photocatalysts were prepared by precipitation and photoreduction method. The as-prepared plasmonic photocatalysts were characterized by XRD, SEM, BET, EDS, UV–vis DRS, XPS and PL. The results show the composite photocatalysts are successfully obtained and obviously exhibit surface plasmon resonance and effectively enhance the separation of h+/e−. The photocatalytic degradation rate of tetracycline (TC) could reach 97.3% in 60min under visible light irradiation and cycled experiments show stably photocatalytic activities. The active species analysis displays holes and superoxide radicals are the main reactive species. Photocatalytic kinetic indicates that the degradation processes obey pseudo first order kinetic equation.
