TiO2, ZnO and nanobimetallic silica catalyzed photodegradation of methyl green

The present works describes a method for degradation and decolorization of methyl green (MG) on semiconducting oxides and nanobimetal (Ag/Pt) doped silica sol–gel powder by using UV and solar light. Bimetallic nanoparticles are the recent research interest because of the high catalytic activity and...

Zusammenfassung:The present works describes a method for degradation and decolorization of methyl green (MG) on semiconducting oxides and nanobimetal (Ag/Pt) doped silica sol–gel powder by using UV and solar light. Bimetallic nanoparticles are the recent research interest because of the high catalytic activity and tunable surface plasmon resonances. In this study the nanobimetal (Ag/Pt) doped silica sol–gel powder were prepared and characterized. Silica sol–gel powder was characterized by FT-IR spectroscopy, SEM with EDX, TEM, DRS and XRD analysis. The results of photodegradation of methyl green on TiO2, ZnO and nanoAg/Pt bimetal doped silica sol–gel powder were presented and compared.
