WebbPhotocatalytic degradation of 1,2-dichlorobenzene using immobilized TiO2/SnO2/WO3 photocatalyst under visible light: Application of response surface methodology Author(s) Nadarajan, R; Abu Bakar, WanAWan; Ali, R; Ismail, R Year. 2024 ... DRUV, PL, FESEM and XPS. Calcination of TiO2 at 950 degrees C resulted in highest activity. WebbThe decrease of PL emission peak intensity with Fe doping revealed the generation of singly charged oxygen vacancies. The H2O2-assisted photocatalytic degradation efficiency of Fe-SnO2 NPs investigated against crystal violet dye indicated an efficiency of 98% for 0.05 M Fe-SnO2 NPs within 30 minutes under visible light illumination.
