摘要

在可见光下正在进行的光催化研究中,已经证明掺杂或杂化催化剂比单独使用单一催化剂更有活性。然而,可见光吸收、表面高能位点数量少以及光产生的光电子空穴对的快速重组等问题阻碍了光催化剂的实际和广泛应用。为了克服这些问题,采用多种方法合成纳米结构杂化催化剂引起了人们的广泛关注。提出了几种制备具有理想结构和形态的光催化剂的方法。类似于部分改性的制备方法可能导致不同的结构和质量。在这方面,开发高效、低成本和快速合成的光催化剂是最需要考虑的问题。本文综述了钒化合物光催化改性的各种方法和机理,以提高其光催化效率。此外,还详细介绍了合成温度、溶液pH和浓度对光催化性能的影响。

Advances in metal-based vanadate compound photocatalysts: synthesis, properties and applications
Among the ongoing research on photocatalysis under visible-light, it has been shown that doped or hybrid catalysts are more active than a single catalyst alone. However, problems including visible light absorption, a low quantity of energetic sites on surfaces, and rapid recombination of the photo-electron hole pair produced by light have prohibited photocatalysts from being used in a practical and widespread manner. To overcome these problems, synthesis of nanostructure hybrid catalyst using several methods has attracted much attention. Several procedures have been suggested for the preparation of photocatalysts with the desired structure and morphology. Preparation methods similar to partial modification may lead to diverse structures and qualities. In this regard, the development of efficient, low-cost photocatalysts and rapid synthesis is the most important issues that should be considered. This review discusses various methods and mechanisms that work with the modification of vanadium compounds as photocatalysts to progress their photocatalytic efficiency. In addition, the effects of synthesis temperature, solution pH and concentration on the photocatalytic performance are also described in detail.
