51 Photocatalytic Generation of Hydrogen from Water over InVO₄ Nanoentities Confined in SBA-15 Available to Purchase

InVO₄ (50 wt%) nanocrystals particles were confined in the pores of SBA-15 mesostructured silica by using the cetyltrimethylammonium bromide-templated hydrothermal strategy. The surface areas, light absorption properties and the thermal stabilities of the prepared photocatalyst could be enhanced by introducing the support of SBA-15. The resulting materials exhibited higher photocatalytic performance for H₂ production in pure water under visible light irradiation compared with InVO₄∕CNTs or bulk-InVO₄. And it is found that a mixed crystal phases (monoclinic and orthorhombic) of InVO₄ obtained at the calcination temperature of 700°C maybe played important role in determining the reaction activity.
