Abstract

Bismuth oxide is prepared by a simple chemical route and it crystallizes in the monoclinic crystal system. The measured optical band gap value of 2.694(1) eV supported that the prepared bismuth oxide can be used as a visible light photocatalyst. The degradation property of bismuth oxide is studied using methyl orange as a model pollutant and a degradation of 85% is achieved in 4 h. The kinetics of bismuth oxide is fitted using pseudo first and second order equations.
氧化铋降解甲基橙
氧化铋是用简单的化学方法制备的,它在单斜晶系中结晶。测得的光学带隙值为2.694(1)eV,表明所制备的氧化铋可以作为可见光光催化剂。以甲基橙为模型污染物,研究了氧化铋的降解性能,在4 h内降解率达到85%。氧化铋的动力学用拟一、二阶方程拟合。
