Au/Ti Synergistically Modified Supports Based on SiO2 with Different Pore Geometries and Architectures

New photocatalysts were obtained by immobilization of titanium and gold species on zeolite Y, hierarchical MCM-48 KIT-6 supports with microporous, mesoporous cubic structure. The samples characterized X-ray diffraction (XRD), N2-physisorption, scanning transmission electron microscopy (SEM/TEM), diffuse reflectance UV–Vis spectroscopy (DRUV-Vis), photoelectron (XPS), Raman photoluminescence spectroscopy. photocatalytic properties evaluated in degradation amoxicillin (AMX) from water, under UV (254 nm) visible light (532 irradiation. higher efficiency best apparent rate constant irradiation for Au-TiO2-KIT-6, while the condition Au-TiO2-MCM-48 sample containing anatase, rutile greatest percent Au metallic clusters found (evidenced XPS). Although significant values obtained, total mineralization was not achieved. These results explained different reaction mechanisms, which act as e− trap generator light.
