Improvement of the Photocatalytic Activity of Au/TiO2 Nanocomposites by Prior Treatment of TiO2 with Microplasma in an NH3 and H2O2 Solution

Plasmonic photocatalytic nanocomposites of TiO2 and Au nanoparticles (NPs) have recently attracted the attention researchers, who aim to improve activity potential NPs. In this study, we report enhancement for a Au/TiO2 nanocomposite prepared by plasma–liquid interaction method using an atmospheric microplasma apparatus. The enhanced is demonstrated degradation methylene blue (MB) in water under both ultraviolet (UV) visible light irradiation. prior treatment with NH3 H2O2 solution found strongly treated NPs, as well synthesized nanocomposite.
