摘要
光催化技术是一种具有广阔应用前景的绿色环境治理技术,而光催化剂则是该技术的关键,且较之传统的高温、常规催化技术及吸附技术有优越的特性。在目前已研发的各种光催化剂中,Bi系半导体光催化剂是具有可见光响应的光催化剂,在可见光下具有良好的光催化性能。本文综述了国内外对铋系光催化剂及其应用研究新进展,并展望了该系列可见光催化剂发展前景。
Photochemical catalytic technology is an investigative hotspot of the field of environmental engineering, and the photoeatalysts is the key of this technology. Bismuth compounds has good performance of photocatalysis under visible -light （λ≥420） , so it is widely attended to and further researched. This paper reports the new development of the visible - light - driven bismuth photoeatalysts and application, and the prospective developments in new visible -light photocatalysts have been anticipated.
