Preparation of Tremella-like BiOBr and Its Photocatalytic Performance

doi:10.7517/j.issn.1674-0475.2014.06.558

Abstract

Abstract:

A solvothermal method to prepare tremella-like BiOBr was developed by using β-CD, Bi(NO₃)₃·5H₂O and KBr as starting materials. The nano BiOBr was characterized by X-ray diffraction, scanning electron microscopy(SEM) and UV-visible. It was found that the micro-morphology of BiOBr was greatly influenced by the amount of β-CD. When the amount of β-CD was 0.4574 g, the morphology of product was tremella-like BiOBr with a highest photocatalytic activity under visible light irradiation.

Key words: β-CD, solvothermal, tremella-like BiOBr, photocatalytic
