Abstract
|
The Ag/RGO/TiO2 nanocomposite was synthesized through an environmentally benign, simple, cost efficient, surfactant-free and green method using Euphorbia helioscopia L. leaf extract as a stabilizing and reducing agent. The E. helioscopia L. leaf extract was used for the reduction of Ag+ ions and GO to Ag NPs and RGO, respectively. The GO/TiO2 and Ag/RGO/TiO2 nanocomposites were characterized by FT-IR, UV-vis, TEM, XRD, SEM, EDS and ICP techniques. The Ag/RGO/TiO2 nanocomposite was highly active for the reduction of 4-nitrophenol (4-NP), congo red (CR) and methylene blue (MB) in aqueous media at an ambient temperature. The Ag/RGO/TiO2 nanocomposite was easily separated and recovered from the reaction mixture by centrifugation and reused for several cycles without any significant loss of catalytic activity
