Abstract:
      In recent years, with the excellent properties of metal oxide composite airgel, the application field is very extensive. In this study, metal oxide composite airgel was prepared by sol-gel method with liquid chemical reaction, Visible, XRD, BET, XPS, SEM, PL and TEM were used to study the band structure and photocatalytic properties of the composite airgel, including the band correlation map, the contact crystal phase, the surface morphology and the hydrogen production rate of the unit matter. The results show that the separation efficiency of energy absorption and electrons and holes in TiO2 composite airgel is higher than that of SnO2 and Al2O3, and the photocatalytic activity and stability of TiO2 composite aerogels Also higher than SnO2 and Al2O3 aerogels.
