Various combinations of TiO2 and SnO2 in binary composites of SnO2/TiO2 and (2-10 wt. %) Co3O4 on SnO2/TiO2 of ternary composite Co3O4/SnO2/TiO2 with were prepared. All the photocatalysts shows anatase crystalline phase and some of appropriate peaks of SnO2 and Co3O4 peaks also present in binary and ternary systems, which is confirmed by X-Ray diffraction analysis. UV-Vis DRS indicated that all ternary composite Co3O4/SnO2/TiO2 showed strong response in visible region and pure materials shows representative band positions. The molecular structure of M-O linkages (Ti-O, Co-O and Sn-O) is studied by FTIR analyses. Other physicochemical techniques such as SEM and PL also confirm the surface property and electronic excitation state. Ternary composite Co3O4/SnO2/TiO2 demonstrates the highest decomposition for simultaneous degradation of reactive orange 30 (RO 30) under solar light. |
