为了生产在可见光下高效工作的光催化剂，产生了许多等离子体光催化剂，其中贵金属纳米颗粒沉积在极性半导体或绝缘体颗粒的表面。在金属-半导体复合光催化剂中，贵金属纳米粒子由于其表面等离子体共振而成为获取可见光的主要成分，而金属-半导体界面则有效地分离了光生电子和空穴。本文综述了近年来制备和表征的各种等离子体光催化剂。
The efforts to produce photocatalysts operating efficiently under visible light have led to a number of plasmonic photocatalysts, in which noble metal nanoparticles are deposited on the surface of polar semiconductor or insulator particles. In the metal-semiconductor composite photocatalysts, the noble metal nanoparticles act as a major component for harvesting visible light due to their surface plasmon resonance while the metal-semiconductor interface efficiently separates the photogenerated electrons and holes. In this article, we survey various plasmonic photocatalysts that have been prepared and characterized in recent years.
