摘要: Photocatalytic degradation of local municipal wastewater and brilliant blue FCF dye were investigated using silver-doped ZnO designer particles. The particles synthesized under mild hydrothermal conditions (T = 150–250∘C, 𝑃=autogeneous, experimental duration 16–24 h) in the presence surface modifiers. resultant products characterized powder XRD, FTIR, Zeta potential, SEM. Various parameters including catalyst amount, light source, pH, photocatalytic time studied to find out their effects on photodegradation efficiency with respect dye. effect these was evaluated chemical oxygen demand (COD) % transmittance analyses. results showed that surface-modified had higher compared reagent-grade
