摘要
研究开发可见光响应的光催化剂一直是光解水制氢的首要目标。近年来通过能带调控等手段实现光催化剂的可见光化被广泛研究,并取得了令人注目的进展。本文综述了通过能带调变实现可见光化的各种手段,包括TiO2掺杂特别是阴离子掺杂、能响应可见光的新型固溶体和单相光催化材料的开发以及Z-型反应系统的构筑,以及通过电子结构的分析阐述其可见光化的机理。
The urgent work for photocatalytically splitting water into H2 and O2 is to develop photocatalysts capable of responding to visible light occupying nearly half amount of solar spectrum. Many ways to make photocatalysts active under visible light have been extensively studied and practiced. In this article, band engineering such as doping with cations and anions for TiO2, solid solution with narrow and wide gap precursor photocatalysts and Z-scheme system are reviewed. The implementation and characterization of different ways and their mechanisms for visualization based on electronic band structure is discussed.
