Improved photocatalytic activities of TiO2/MoO3/Au nanocomposite prepared by hydrothermal method

Abstract

The synthesis of TiO₂/MoO₃/Au nanocomposite has been carried out to study its photocatalysis activity. A hydrothermal technique was used to systematically incorporate titanium dioxide (TiO₂), molybdenum trioxide (MoO₃), and gold nanoparticles (Au NPs) to produce a synergistic nanostructured material. The analysis of prepared nanocomposite was performed using several characterization methods. UV-visible spectroscopy is used to examine the existence of materials and optical absorption. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were among the methods used to study the crystalline phases and surface morphologies. Methylene blue organic pollutants were used to evaluate the photocatalytic activity of the resulting TiO₂/MoO₃/Au nanocomposites under visible light irradiation. The TiO₂/MoO₃/Au composite showed significant photocatalytic performance among the three composites.
