摘要
为了解决日益严重的环境污染问题和能源问题,越来越多的研究者将精力投入到ZnO、CdS、TiO_2和BiVO_4等半导体材料的研究中。其中,TiO_2以优异的氧化能力、较强的化学稳定性、较低的价格以及无毒性吸引了广泛的目光。针对近年来TiO_2的光催化性能研究及其改性方法的研究进展,以及应用热点进行了综述,并对如何进一步提升其性能进行了展望。
Semiconductor photocatalysts like ZnO, CdS, TiO2 and BiVO4, which have long been studied to alleviate the deterioration of problems created by pollutants and energy crisis, have attracted increasing attention. Titanium dioxide （TiO2）, a very important oxide semiconductor, is regarded as a suitable material for extensively investigating in the photocatalytic field owing to its chemical stability, high chemical inertness, nontoxicity, and low cost. In this paper, the research development of its photocatalytic performance, modification methods and application focus are summarized in detail. Finally, the development tendency of how to further boost performance is predicted.
