The invention discloses a mesoporous
silicon dioxide compound photocatalyst. In the mesoporous
silicon dioxide compound photocatalyst,
silicon dioxide is used as a carrier, a photosensitive
silane coupling agent is doped in a framework in the carrier, and
titanium dioxide is loaded in nano hole channels of the carrier. The invention also provides a preparation method of the mesoporous
silicon dioxide compound photocatalyst. The preparation method comprises the steps: firstly preparing the photosensitive
silane coupling agent by using a high-temperature
pyrolysis method, preparing a photosensitive
silane coupling agent doped
mesoporous silica material by using an in-situ loading method, performing a hydrothermal method on
titanium oxide, and introducing
titanium oxide after subjected to the hydrothermal method into photosensitive
silane coupling agent doped
silicon oxide hole channels in the framework by adopting a loading manner to finally obtain the mesoporous
silicon oxide compound photocatalyst. The photosensitive
silane coupling agent on the surface of the photocatalyst has the relatively good complexing capacity on
metal ions, the high dispersion and the small grain size loading of a
semiconductor-
titanium dioxide on the photosensitive
silane coupling agent-mesoporous
silicon oxide compound material is realized, and therefore, the material has the very good circulation
pollutant disposal capacity of
pollutant enrichment firstly and
pollutant degradation.
