摘要/Abstract

摘要：

发展高效的可见光催化剂是太阳能化学利用的一个挑战. 本文采用简单的混合方法, 制备了WO₃和Fe₂O₃的混合物, 研究了该复合氧化物在H₂O₂存在下光催化降解有机染料X3B的活性. 实验表明, 催化剂的光催化活性与其煅烧温度和Fe₂O₃含量有关. 最佳煅烧温度和Fe₂O₃含量分别等于400 °C 和1.0% (w). 根据自由基捕获电子顺磁共振(EPR)波谱分析, 复合氧化物产生羟基自由基的量远高于Fe₂O₃和WO₃. 我们推测, 这种协同效应来源于WO₃和Fe₂O₃之间的电荷转移, 从而加快半导体光生载流子的分离和X3B的光催化降解.

Abstract:

Development of a highly active visible-light-driven photocatalyst is a challenge for chemical use of solar energy. In this work, WO₃ was simply mixed with Fe₂O₃, and used thereafter for the photocatalytic degradation of organic dye X3B in the presence of H₂O₂. It was observed that the composite activity was greatly influenced by the catalyst sintering temperature, and by Fe₂O₃ content in the mixed oxide. The optimum sintering temperature and Fe₂O₃ loading were 400 ° C and 1.0% (w), respectively. Through a spin trapping electron paramagetic spectroscopy, it was found that the composite produced a significantly larger amount of hydroxyl radicals, in relative to Fe₂O₃ and WO₃. It is proposed that the observed synergistic effect between Fe₂O₃ and WO₃ is due to the charge transfer between the two oxides, improving the separation of the photogenerated charge carriers, and thus accelerating the photocatalytic degradation of X3B.
