Environmental and energy problems have drawn much attention owing to rapid population growth and accelerated economic development. For instance, photocatalysis, “a green technology”, plays an important role in solar‐energy conversion owing to its potential to solve energy and environmental problems. Recently, many efforts have been devoted to improving visible‐light photocatalytic activity by using titanium dioxide as a photocatalyst as a result of its wide range of applications in the energy and environment fields. However, fast charge recombination and an absorption edge in the UV range limit the photocatalytic efficiency of TiO2 under visible‐light irradiation. Many investigations have been undertaken to overcome the limitations of TiO2 and, therefore, to enhance its photocatalytic activity under visible light. The present literature review focuses on different strategies used to promote the separation efficiency of electron–hole pairs and to shift the absorption edge of TiO2 to the visible region. Current synthesis techniques used to elaborate several nanostructures of TiO2‐based materials, recent progress in enhancing visible photocatalytic activity, and different photocatalysis applications will be discussed. On the basis of the studies reported in the literature, we believe that this review will help in the development of new strategies to improve the visible‐light photocatalytic performance of TiO2‐based materials further.

用于光催化应用的二氧化钛纳米材料的最新进展

由于人口的快速增长和经济的发展,环境和能源问题引起了人们的极大关注。例如,“光催化”是一种“绿色技术”,因为它具有解决能源和环境问题的潜力,因此在太阳能转换中起着重要作用。最近,由于其在能源和环境领域的广泛应用,人们已经通过使用二氧化钛作为光催化剂致力于改善可见光的光催化活性。但是,快速的电荷复合和在UV范围内的吸收边缘限制了TiO 2在可见光照射下的光催化效率。为了克服TiO 2的局限性,已经进行了许多研究。因此,以增强其在可见光下的光催化活性。本文献综述集中于用于提高电子-空穴对的分离效率以及将TiO 2的吸收边缘移至可见光区域的不同策略。将讨论用于详细阐述TiO 2基材料的几种纳米结构的当前合成技术,在增强可见光催化活性方面的最新进展以及不同的光催化应用。根据文献报道的研究,我们认为本综述将有助于开发新的策略,以进一步改善TiO 2基材料的可见光光催化性能。
