The growth mechanism of titania/hydroxyapatite and its application in the photodegradation of methyl orange dye under UV irradiation

In this work, titania/hydroxyapatite (TiO2/HAP) composite materials were synthesized via a wet chemistry method. Morphological field emission scanning electron microscopy and electronic differential system field analysis revealed the growth mechanism that TiO2 began to divorce from surface on HAP wi...

Morphological field emission scanning electron microscopy and electronic differential system field analysis revealed the growth mechanism that TiO2 began to divorce from surface on HAP with the Ti content of 2.60% while separated from the surface of HAP with the Ti content of 4.83%. Furthermore, Fourier transform infrared spectroscopy verified that the crystal structure of TiO2/HAP remained stable in the degradation process of MO. Especially, the TiO2/HAP has a good photocatalytic activity and photostability with the Ti content of 2.55%.
