| 中文摘要: |
| 目前,BiOX(X = Cl、Br、I)基化合物作为一类新型的光催化剂,正受到越来越多的关注。合适的带隙和X元素的可调性使BiOX能够适应多种光催化反应,其独特的层状结构的半导体特性,使BiOX基复合光催化剂表现出较强的光生电子和空穴分离,从而BiOX基复合光催化剂在许多反应中都表现出较优异的活性。然而,BiOX材料本身还存在光吸收能力弱、载流子分离效率低等缺点,需要对其改性,从而获得催化活性更强的BiOX基复合光催化剂。本文着重介绍了BiOX基复合光催化剂的改性手段,综述了BiOX基复合材料在析氢、固氮、CO2还原等能源光催化领域及其在光催化降解废水中有机污染物方面的应用进展。 |
| 英文摘要: |
| At present, BiOX(X = Cl、Br、I) based compounds are a new class of photocatalysts and have received more and more attention. Suitable band gap and tunability of X element enable BiOX to adapt to a variety of photocatalytic reactions. Its unique layered structure and semiconductor properties of indirect band gap enable BiOX -based composite photocatalysts to exhibit excellent photogenerated electron and hole separation efficiency. Therefore, BiOX based composite photocatalysts have shown excellent activity in many photocatalytic reactions. However, the BiOX material itself still has the disadvantages of weak light absorption capacity and low carrier separation efficiency, so it needs to be modified to obtain BiOX composite photocatalyst with stronger catalytic activity. In this paper, various modification methods of BiOX based composite photocatalysts are introduced, and the application progress of BiOX based composite photocatalysts in the field of photocatalytic hydrogen evolution, nitrogen fixation, CO2reduction and photocatalytic degradation of organic pollutants in wastewater was reviewed. |
