With the rapid development in the field of smart materials, photochromic materials have a wide range of application prospects. Titanium dioxide (TiO2), as a common semiconductor material, is widely studied in the preparation of photochromic materials. However, a single TiO2 material has some limitations in photochromic performance. Therefore, the introduction of a multi-faceted composite approach becomes an important way to enhance the performance of the materials. The aim of this paper is to review the latest research progress of TiO2-based multi-composite photochromic materials and to explore the effects of different composite systems on photochromic properties. This paper first introduces the basic properties and application areas of TiO2 photochromic materials, which provides a basis for the subsequent discussion. Second, TiO2-based binary composite photochromic materials are classified and discussed in detail, including TiO2/metal, TiO2/metal oxide, and other TiO2-based binary composites. Then the research progress of TiO2-based ternary composite photochromic materials is discussed. Finally, the future development direction of TiO2-based multi-composite photochromic materials is envisioned. This paper serves as a reference for future research on composite photochromic materials, promotes the development of photochromic materials in practical applications, and facilitates progress and innovation in the field of smart materials.
