Efficient Solar Light Photocatalyst Made of Ag₃PO₄ Coated TiO₂-SiO₂ Microspheres.

ABSTRACT: Solar light active photocatalyst was prepared as silver phosphate (Ag₃PO₄) coating on titania-silica (TiO₂-SiO₂) microspheres. Titania-silica microsphere was obtained by spray drying TiO₂-SiO₂ colloidal solutions, whereas Ag₃PO₄ was applied by wet impregnation. XRD on the granules and SEM analysis show that the silver phosphate particles cover the surface of the titania-silica microspheres, and UV-visible diffuse reflectance analysis highlights that Ag₃PO₄/TiO₂-SiO₂ composites can absorb the entire visible light spectrum. BET measurements show higher specific surface area of the composite samples compared to bare Ag₃PO₄. Photocatalytic ac
