Abstract

Abstract: As a visible light-responsive element semiconductor photocatalyst, red phosphorus has the advantages of low cost, chemically inactive, low toxicity and suitable band gap. However, there are also some problems, such as small specific surface area of commercial red phosphorus and serious photogenerated electron-hole recombination, which need to be modified to improve the photocatalytic performance. This paper focuses on the research progress of red phosphorus in the modification of surface morphology, surface modification, composite regulation and heterojunction of construction, and the application of modified catalysts in the degradation of organic pollutants and the production of hydrogen production. Finally, it is pointed out that the future research direction is to modify red phosphorus by various means at the same time, to expand the application of red phosphorus in the field of photocatalysis and to explore the mechanism of red phosphorus in depth and so on.

Key words: red phosphorus, photocatalyst, visible light, heterojunction, surface modification

摘要： 红磷作为一种可见光响应的半导体光催化剂，具有廉价易得、化学性质稳定、低毒以及合适的带隙等优点，但也存在商业红磷比表面积小以及光生电子-空穴对复合严重等问题，需要对其进行改性以提高光催化性能。本文着重评述了红磷在形貌调控、表面修饰、复合调控和构建异质结等改性手段方面的研究进展以及改性催化剂在降解有机污染物、分解水制氢等方面的应用。最后指出未来的研究方向在于同时用多种手段改性、拓展红磷在光催化领域的应用和深入进行机理探索等方面。
