Characterization of TiO2 and an as-prepared TiO2/SiO2 composite and their photocatalytic performance for the reduction of low-concentration N-NO3− in water

Excessive N-NO 3 − water pollution has become a widespread and serious problem that threatens human and ecosystem health. Here, a TiO 2 /SiO 2 composite photocatalyst was prepared via the sol–gel/hydrothermal method. TiO 2 and TiO 2 /SiO 2 were characterized by X-ray diffraction (XRD), UV–Vis differ...
