title: Preparation and enhanced catalyst effect of assembled hydroxylapatite microsphere chains.
abstract: The hydroxyapatite (HAP) assembled microsphere chains with high surface area and large size in length (20-35 microm) were prepared by a facile and efficient cooperation template method. The products were characterized by XRD, TEM, SEM, FT-IR, EDS, BET, etc. The possible mechanism for the formation of HAP assembled microsphere chains was also discussed. In addition, the products were used as carried materials to synthesize HAP/TiO2 (anatase phase) composite catalyst, the bandgap of TiO2 nanomaterials was enlarged. The degradation speed of methyl orange (MO) was increased to 150% when using the composite as catalyst compared with using TiO2 nanoparticles. At the same time, the composite catalyst can be separated and recycled more easily than existing carry materials.
