中文摘要:
      贵金属与半导体复合形成的催化剂具备肖特基结结构,该结构具有整流特性和较低的界面电压,可以调控光生电子的产生和流向,使电子和空穴更有效地分离,提升光催化性能。综述了近年来肖特基半导体光催化剂的研究进展,分析了晶面沉积、形貌结构、表面等离子体效应及共掺杂等因素对该类催化剂性能的影响,从降解污染物、制氢、二氧化碳还原等方面阐述了这类催化剂在环境控制领域的实际应用,并提出了势垒高度、产物控制及催化剂循环利用等潜在的研究方向。肖特基型光催化剂独特的性质将使其成为新的研究热点,得到更深入的研究和应用。
英文摘要:
      The combination of noble metal with semiconductor can produce the Schottky junction. Schottky junction possesses rectification property and low interface voltage, which can be uesd to control the production and flow of photoinduced electrons. Therefore, over the photocatalyst with Schottky junction, the separation of photoinduced electrons and holes can be effectively promoted and the photocatalytic efficiency is expected to be improved. In this paper, the progress in Schottky semiconductor photocatalyst is summarized. The effects of crystal facet deposition, morphological structure, surface plasmon resonance and co-doping on the photocatalytic performance of the Schottky junction photocatalyst are analyzed. The application prospect in environmental control including the degradation of pollutants, hydrogen production and carbon dioxide reduction are discussed. The research directions of barrier height, product control and the reusing of catalyst are proposed. The unique property of Schottky photocatalyst can lead to a research hot spot and more applications are also expected in the near future.
