TiO2 that exists in different phases such as anatase, rutile, and brookite is one of the most promising photocatalysts. These phases show different properties and photocatalytic performances. It is well known that mixed-phase TiO2 has enhanced photocatalytic activity compared to pure-phase TiO2. In the past two decades, many research works focusing on the synthesis of different kinds of mixed-phase TiO2 and their applications to photocatalysis have been done. In this chapter, we introduce three main types of TiO2 phases as mentioned above, containing their structural properties, stability, phase transformation, and photocatalytic activity. Then we pay more attention to the synthesis of the mixed-phase TiO2 and detailedly introduce six preparation methods, which are hydrothermal method, solvothermal method, microemulsion-mediated solvothermal method, sol–gel method, solvent mixing and calcination method, and high-temperature calcination method. After that, we comprehensively highlight three different kinds of applications of the mixed-phase TiO2 in the photocatalysis field, including photocatalytic production of hydrogen, reduction of CO2 with water, and degradation of organic pollutants. As the photocatalytic activity of the mixed-phase TiO2 is usually higher than the single-phase TiO2, we discuss the mechanism for the enhancing effects of the mixed phases. Due to the limit of the present science and technology, the challenges of mixed-phase TiO2 still remain. In the end, we summarize the existing problems of this kind of nanomaterials and put its application prospects forward.
