Abstract
Visible-light induced degradation of an aqueous mixture containing MO and RhB on well-defined α-Fe2 O3 nanocrystals shows that MO degradation is more favorable and such selectivity on the {012} facet is greater than that on {001}. The origin of selectivity is rationalized as the inherent surface structural difference and preferential molecular adsorption.
摘要
在明确的 α-Fe2 O3 纳米晶体上，可见光诱导降解含有 MO 和 RhB 的水溶液混合物表明，MO 的降解更为有利，并且在{012}面上的这种选择性大于在{001}面上的选择性。选择性的起源可以合理地解释为固有表面结构差异和优先的分子吸附。
