Photocatalytic Performance and Mechanism Research of Ag/HSTiO₂ on Degradation of Methyl Orange.

ABSTRACT: The Sol-gel method is successfully used to prepare high specific surface area TiO₂ (HSTiO₂). Then, the photodeposition method is used to composite silver particles with HSTiO₂. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller, and UV-vis spectroscopy are used to characterize the Ag/HSTiO₂ nanocomposites. It can be concluded that the prepared TiO₂ has a large specific surface area, reaching 125.5 m² g^-1. Additionally, the addition of silver particles successfully broadens the photoresponse range from the UV region to the visible light region. In order to evaluate the photocatalytic activity of Ag/HSTiO₂, we conducted the methyl orange degradation t
