Abstract

Cage-like Bi₂MoO₆ hollow spheres (C-BMO) were first prepared by a hard-template method. The C-BMO possessed the size of 1.3-1.6 μm and the band-gap of 2.56 eV. The C-BMO exhibited much higher efficiency than the Bi₂MoO₆ synthesized by solid state reaction in the degradation of phenol under visible-light irradiation due to its larger specific surface area. The mechanisms for the degradation of phenol over the C-BMO were investigated, which revealed the predominant role of both the ^{{radical dot}}OH radicals in the degradation of phenol and the photoinduced electrons in the derivation of ^{{radical dot}}OH radicals.
