Size-controlled gold nanoparticles on octahedral anatase particles as efficient plasmonic photocatalyst.

ABSTRACT: Octahedral anatase particles (OAPs), prepared by ultrasonication-hydrothermal reaction (US-HT), were modified with 2 wt% of gold by photodeposition. Conditions of US-HT process such as durations of US and durations of HT were varied to obtain OAPs products different by physicochemical and morphological properties. Au/OAPs samples were characterized by X-ray diffraction (XRD), scanning transmission electron microscopy (STEM), X-ray photoelectron spectroscopy (XPS) and diffuse reflectance spectroscopy (DRS). The photocatalytic activity was tested under UV irradiation for decomposition of acetic acid (CO₂ system) and dehydrogenation of methanol (H₂ system) under aerobic and anaerobic conditions, respectively, and for oxidation of 2-propanol under visible light irradiatio
