摘要：
The degradation of glutamic acid by BiOBr under both UV and visible irradiation was investigated and compared with degradation by TiO2/UV. Analysis of the reaction rates and the distribution of intermediates was used to show that both BiOBr systems, unlike the TiO2 system, catalyze direct substrate oxidation by valance band holes.
