英语翻译 Forbidden-band-width of mono-clinic phase of bismuth vanadate(mBiVO4)is high enough to 2.3-2.4 eV，it could be valence band to carry out entirely that hole band degrade organic pollutants，and the conduction band possesses high oxidizability to make for reduction of photoinduced electron，and oxidation potential of its valence band with 2.4 eV nearby could achieve decomposition of water and degradation of organic pollutants under visible light.mBiVO4 was reviewed in this paper，that apply for research on degradation of pollutants，photodecomposition of aquatic oxide，photoelectric chemical dissociation of water，and the research on application prospect of photocatalytic degradation organic matter.
MnO2的禁带宽度是多少？ 可能要看一下天津大学学报了，下面是网址，不过要付费。http：//www.cnki.com.cn/Article/CJFD2002-TJDX200201027.htm
