摘要/Abstract

摘要：

本文通过水热法一步合成了还原氧化石墨烯(RGO)-BiOBr纳米复合体，并进一步对其进行磷酸修饰. 主要研究了所获得的纳米复合体的光电化学性质. 结果表明，与纯BiOBr相比，RGO-BiOBr复合体的光电流密度明显提高. 适量磷酸修饰后，其光电流密度进一步得到提高. 基于羟基自由基等测试结果，分析认为磷酸修饰的RGO-BiOBr纳米复合体光电流密度的提高主要归因于两方面：一是复合的还原氧化石墨烯能够接受光生电子，加快电子的转移，进而促进光生电荷的有效分离；二是复合体表面修饰的磷酸在溶液中电离形成负场，能够起到诱导光生空穴的作用，进一步促进了光生电荷的分离.

Abstract:

The RGO-BiOBr nanocomposites have been successfully synthesized by a hydrothermal process, and then modified with phosphorous acids. The photoelectrochemical properties of the fabricated RGO-BiOBr nanocomposite films were studied. The results indicate that the photocurrent densities of RGO-BiOBr were much larger compared with those of the bare BiOBr, and interestingly, the photocurrent densities were further improved after phosphate modification. Based on the analyses of the produced hydroxyl radical amounts, the enhanced photocurrent densities could be attributed to the introduction of RGO and to the formed negative fields of modified phosphate groups, which are favorable for electrons to be transferred and for holes to be trapped, respectively, leading to promoted charge separation.

Key words: RGO-BiOBr nano-composite, Phosphoric acid modification, Photogenerated charge property, Photoelectrochemistry
