摘要
随着能源需求日益增长,寻找可持续发展的再生能源越来越成为重要任务.光催化分解水制氢因其清洁环保的太阳能利用而受到广泛关注.TiO_(2)作为一种应用于光催化领域的前沿材料,受到了广泛的关注.TiO作为光催化剂,以无毒、价廉、稳定性好和光催化活性高等优点被广泛应用于分解水制氢等领域.但由于其禁带宽度较宽和光生电子-空穴对复合率较高,TiO_(2)作为光催化剂的性能普遍受到限制.许多不同的研究致力于克服这些问题,使得光催化性能得到显著改善.综述了近年来TiO_(2)光催化材料的析氢反应的研究进展,重点讨论了关于复合材料的元素组分、掺杂以及光敏化对TiO_(2)光催化活性的影响,对每种复合材料的优越性和局限性进行了评述.最后指出了TiO_(2)作为光催化剂在未来发展中面临的问题以及发展前景.
With the increasing demand for energy, it has become essential to find renewable energy for sustainable development.Photocatalytic hydrogen production from water decomposition has attracted extensive attention due to its clean and environment-friendly solar energy utilization.As a frontier material used in the field of photocatalysis, TiO_(2) has received extensive attention.As a photocatalyst, TiO_(2) has been widely used in the field of hydrogen production from water decomposition due to its non-toxic, low price, good stability and high photocatalytic activity.However, due to its wide band gap and high recombination rate of photogenerated electron hole pairs, the performance of TiOas a photocatalyst is generally limited.Many different researches have been devoted to addressing these problems, and the photocatalytic performance has been significantly improved.The research progress of hydrogen evolution reaction of TiO_(2) photocatalyst materials in recent years is reviewed, with emphasis on the influence of element composition, doping and photosensitization of composite materials on TiOphotocatalyst activity.The advantages and limitations of each composite material are reviewed.Finally, the problems and prospects of TiO_(2) as a photocatalyst in the future development are pointed out.
