Abstract

One-component semiconductor photocatalysts have low photocatalytic life because of the recombination of photo generated electrons and holes. Through compositing of two components can significantly improve the photocatalytic efficiency. In this paper, the water bath heating method has been used to synthesise alumina doped zinc oxide nanoparticles supported on hydroxyapatite (ZAO/HAP) nanocomposite materials. The ZAO/HAP nanocomposite materials have better photocatalytic efficiency than ZAO nanoparticles. The morphologies of HAP have significant impact on photocatalytic efficiency of ZAO/HAP composite catalysts.
