摘要:

光/光电催化引起了全球研究人员的极大关注,通过光/光电催化可以进行水处理、水分解制氢和有机合成,从而解决能源和环境问题。 用于能源和环境应用的半导体二氧化钛(TiO2)纳米材料光电催化剂引起了广泛的研究兴趣,然而,主要的应用瓶颈是其较大的带隙。 在基于TiO2的光催化材料中引入缺陷是改善光/光电催化性能的一种有前途的策略,对TiO2的缺陷进行工程改造可以拓宽光电响应并提高电荷分离效率。 本综述先从光/光电催化反应机理上展开,提出了缺陷型TiO2的引入可以提高其光/光电催化活性,并系统总结了一些用于制备缺陷或黑色TiO2的常用合成方法和缺陷工程策略,随后,详细阐述了缺陷TiO2在光/光电催化应用方面的最新进展。 最后,对缺陷TiO2在光/光电催化方面的研究简要总结,并提出了潜在的发展前景。

Abstract:

Photocatalysis/photoelectrocatalysis has attracted great attentions from researchers around the world because of its application in water treatment, water splitting and organic synthesis to solve energy and environmental problems. Many researchers are interested in titanium oxide (TiO2) nanomaterial as catalytic nanomaterials used in energy and environmental fields. However, the main bottleneck is that it has comparatively big bandgap. The application of photocatalytic materials based on defected TiO2 is a promising strategy to improve the catalytic performance. The modification of TiO2 defects can broaden the photoelectric response and improve charge separation efficiency. In this review, we first start with the photocatalysis/photoelectrocatalysis reaction mechanism, propose that the introduction of defective TiO2 can improve its photocatalysis/photoelectrocatalysis activity, systematically summarize some common synthesis methods and defect engineering strategies for the preparation of defective or black TiO2, and then elaborate the latest progress of defective TiO2 in photocatalysis/photoelectrocatalysis applications. Finally, the research on the photocatalysis/photoelectrocatalysis of defective TiO2 is briefly summarized, and the potential development prospects are proposed.
