The TiO2/hydroxyapatite (HAp) composite has attracted much attention as a photocatalyst for pollution treatment in water or air because this composite can improve the properties of pure TiO2 including a low efficiency, narrow light response range, low adsorption capacity for hydrophobic contaminants, and difficult recovery of TiO2 particles after using in Aquarius environment. To obtain the best composite containing the two components including TiO2 and HAp, the role of HAp in TiO2/hydroxyapatite photocatalytic material should be analyzed and evaluated. This chapter will significantly present a review of the role of HAp in the TiO2/hydroxyapatite composite including the adsorption ability of contaminations and the promoted impacts of HAp component.
