摘要: The photocatalyst materials correlation with the radiation scenario and pollutant molecules can have a significant influence on overall photocatalytic efficiency. This work aims to outline significance of optimizing components mass ratio into tandem structure in order increase activity toward removal. ZnO_SnO2 TiO2_SnO2 structures were obtained by doctor blade technique using different ratios between components. samples contain metal oxides crystalline morphology is influenced main component. was tested three scenarios (UV, UV-Vis, Vis) two (tartrazine acetamiprid). results indicate that wavelength molecule. exhibit 90% efficiency under UV presence tartrazine, while 73% same experimental conditions. kinetic evaluation (2:1) higher reaction rate comparing (1:2) acetamiprid.
