Photocatalytic Activity of TiO₂-Calcium Phosphate Nanocomposite on the Removal of Methylene Blue in Aqueous Suspension

Abstract:

The TiO₂-calcium phosphate (TiO₂/CP) nanocomposites with different ratios were prepared by precipitation of calcium phosphate in the presence of nano-sized TiO₂. The products were characterized by BET, XRD, SEM and EDX techniques. Photocatalytic activity of the nanocomposites was evaluated as a rate constant of decomposition reaction of methylene blue (MB) in aqueous suspensions under UVA irradiation. It was observed that all of the nanocomposites showed higher photocatalytic activity in comparison to pure TiO₂ catalyst. In particular, the rate constant photodecomposition of MB on TiO₂/CP composite at 9:1 ratio (w/w) was above five times higher than on pure TiO₂.
