Abstract

TiO2-based catalysts with various surface heterostructures (0D, 1D, 2D, and 3D) have been widely researched owing to their cost-effectiveness, high stability, and environmentally friendly nature, and can be used for many applications in various fields, including hydrogen production and pollutant degradation. However, there are also many existing problems limiting their practical application, such as their large band gap and rapid electron–hole recombination rate. Owing to the abundance of recent achievements in materials science, we will summarize the recent structural engineering strategies which provide favorable photocatalytic activity enhancements, such as enhanced visible light absorption, stability, an increased charge–carrier separation rate and improved specific surface area. Among the various structural engineering methods in this review, we will introduce TiO2-based materials with different dimensional structures. Meanwhile, we also discuss recent achievements in synthesis methods and application of TiO2-based catalysts in various fields. We aim to display a comprehensive overview which can be a guide for the development of a new generation of TiO2-based catalysts according to their structural design for enhanced solar energy conversion.

用于光催化应用的各种结构的 TiO2 基催化剂：综述

具有各种表面异质结构（0D、1D、2D 和 3D ）的 TiO2 基催化剂因其成本效益高、稳定性强和环境友好等特点而被广泛研究，并可用于制氢和污染物降解等多个领域。然而，目前也存在许多问题限制了它们的实际应用，例如它们的带隙过大、电子-空穴重组速率过快等。鉴于近年来材料科学领域取得的丰硕成果，我们将总结近期的结构工程策略，这些策略可提高光催化活性，如增强可见光吸收、稳定性、提高电荷载流子分离率和改善比表面积。在综述的各种结构工程方法中，我们将介绍具有不同尺寸结构的基于 TiO2 的材料。同时，我们还将讨论基于 TiO2 的催化剂在合成方法和各领域应用方面的最新成果。我们的目的是提供一个全面的综述，为根据结构设计开发新一代基于 TiO2 的催化剂提供指导，以提高太阳能转化率。
