摘要: Abstract In this study, the Ag/AgCl/WO 3 plasmonic Z-scheme photocatalysts with different contents of Ag/AgCl nanoparticles (NPs) were prepared through a facile ultrasonic precipitation method in geothermal water, wherein water served as chlorine source. Then photocatalytic activity was investigated by degradation 4-Aminobenzoic acid (4-ABA) under visible-light irradiation. It found that as-prepared 50 wt% photocatalyst showed highest efficiency 25.12 and 3.53 times higher than those pure WO Ag/AgCl, respectively. The active species trapping experiments indicated h + ·O 2 − key factors 4-ABA photodegradation process. possible mechanism reaction for proposed based on systematical characterizations. We hope paper could give new ideas further exploiting energy to design fabricate highly efficient visible-light-driven environmental remediation.
