| Abstract: | Ag3PO4/TiOxNy photocatalysts are prepared by a sol-gel method.The physical properties and active species of the as-prepared samples are characterized by N2 sorption analysis,X-ray diffraction(XRD),UV-Vis diffuse reflectance spectroscopy(UV-Vis DRS),TPD-MS and ESR.Visible-light photocatalytic decomposition of gaseous benzene over the Ag3PO4/TiOxNy catalysts was investigated.The results showed that the catalytic and structural properties of TiOxNy were improved by Ag3PO4 modifying.When compared to unmodified ... |
