Özet
Titanium dioxide shows tremendous potential for the decomposition of organic
pollutants under UV and visible light irradiation. In this study TiO2 nanospheres @ mesoporous
silica nanospheres (TiO2@SiO2) photocatalyst was synthesized by the sol-gel method. The
synthesized TiO2/SiO2 photocatalyst was decorated by Ag nanoparticle. The decorated TiO2@SiO2–
Ag photocatalyst by a hydrothermal method was characterized by scanning electron microscope
(SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The SEM results
show that TiO2@SiO2–Ag nanospheres photocatalyst was uniformly formed. The EDS analysis
proves that the nanospheres photocatalyst consists of Ti, Si, O, and Ag. The TiO2@SiO2–Ag
nanospheres photocatalyst exhibited better photocatalytic performance for the degradation of
methylene blue under direct UV illumination
