Titanium dioxide mesocrystal,as a new type of semiconductor material,is three-dimensional ordered aggregate formed by oriented self-assembly of primary nanocrystal.Because of its unique crystallization method,its properties are different from those of traditional TiO2 materials.The morphology and structure of TiO2 mesocrystal obtained by the same synthesis method are quite different,and the properties and applications of TiO2 mesocrystal with the same morphology and structure are also very different.This article outlined the formation mechanism of mesocrystal briefly and summarized the preparation methods of TiO2 mesocrystal,such as water/solvothermal method,topological transformation method,inverse microemulsion method,etc.,as well as the photocatalytic and electrocatalytic performance of prepared TiO2 mesocrystal.Finally,the application prospects and research directions of TiO2 were discussed.
