Summary: | “Together we can make the difference”. A quaternary TiO
2
/ZnO/RGO/Ag nanocomposite exhibits enhanced photoactivity compared to TiO
2
/ZnO/RGO and TiO
2
/ZnO for the degradation of rhodamine B under visible light. The quaternary composite was synthesized
via
facile microwave irradiation of dispersed TiO
2
/ZnO and RGO/Ag nanocomposites. X-ray diffraction analysis and high-resolution transmission electron microscopy revealed the presence of TiO
2
, ZnO, RGO and Ag in the composite. Photoelectrochemical measurements and time correlated single photon counting (TCSPC) analysis confirmed that the presence of RGO sheets and Ag enhanced the photocatalytic properties of the nanocomposite. The enhanced charge separation and the low recombination rate of photogenerated charge carriers in the composite with the assistance of excellent co-catalysts, RGO and Ag, have also been investigated. |
