铜及铜基化合物改性TiO_(2)在光催化产氢领域中的研究进展

Research Progress of Copper and Copper-based Nanoparticles Modified TiO_(2) in Photocatalytic Hydrogen Production

伴随着社会的快速发展,人们对于能源的需求也日益增加,但是传统能源始终会面临着资源枯竭的问题。在众多绿色环保、可持续新能源选项中,半导体光催化制氢因其可利用清洁可再生的太阳能制取高效清洁氢能,有望解决能源紧缺和环境污染问题,成为最有应用前景的技术之一。而在种类繁多的半导体光催化材料中,二氧化钛(TiO_(2))因其良好的物理和化学性质从而占据了主导地位,得到了研究人员的广泛关注。同时储量丰富、价格低廉的铜(Cu)及Cu基化合物作为助催化剂在催化领域的应用也引起了科研人员的极大兴趣。本文综述了以Cu基材料为主,通过修饰或改性TiO_(2)光催化剂,以提高其光催化活性的研究现状。包括光催化剂的设计、制备及产氢机制,并提出了目前光催化过程中所存在的一些问题,为光催化的发展贡献绵薄之力。

With the rapid development of society,people's demand for energy is also increasing,but the traditional energy will always face the problem of resource exhaustion.Among many green and sustainable new energy options,producing hydrogen by semiconductor photocatalysts is expected to be one of the most promising technologies because of its utilization of clean and renewable solar energy to produce efficient and clean hydrogen energy.Titanium dioxide(TiO_(2))occupies a dominant position among many photocatalytic materials,which has been widely studied due to its unique physical and chemical characteristics.Meanwhile,the abundant and cheap copper(Cu)and Cu-based compounds as cocatalysts in the field of catalysis have aroused great interest of researchers.This paper reviews the research status of modifying TiO_(2)photocatalysts by Cu-based materials to improve their photocatalytic activity,including the design,preparation and hydrogen production mechanisms of photocatalysts.Some problems in photocatalysis are put forward,which will contribute to the development of photocatalysis.
