采用简易化学蚀刻法制备的bii /Bi2O3异质结构对苯酚和4-氯苯酚（4-CP）具有良好的光催化活性。bii /Bi2O3样品的光催化性能的增强是由于形成了bii -Bi2O3异质结导致的电子空穴对的有效分离。研究了BiOI含量与光催化活性的关系，并提出了一种光生电荷转移工艺。(C) 2010 Elsevier B.V.版权所有
BiOI/Bi2O3 heterostructures, prepared by a facile chemical etching method, exhibit excellent photocatalytic activities on the degradation of phenol and 4-chlorophenol (4-CP). The enhanced photocatalytic performance of BiOI/Bi2O3 samples is attributed to the efficient separation of electron-hole pairs caused by the formation of BiOI-Bi2O3 heterojunction. The relationship between BiOI amounts and photocatalytic activities was investigated, and a photogenerated charge transfer process was proposed. (C) 2010 Elsevier B.V. All rights reserved.
