Facile synthesis of spherical nano hydroxyapatite and its application in photocatalytic degradation of methyl orange dye under UV irradiation

Abstract

Hydroxyapatite (HAP) nanoparticle as photocatalyst was synthesized by a wet chemistry synthesis method. Morphological SEM analysis revealed that the presence of HAP is highly dispersed nano-sphere particles which size from 20 to 60nm. The HAP's photocatalytic activity was examined by photocatalytic degradation of methyl orange (MO) dye. The MO degradation over the HAP was indicated that MO and its intermediate (benzene contamination) were mostly degraded by HAP nano-sphere within 120min under UV irradiation.
