| With the continuous development of the global economy and the significant improvement of people's living standards, energy conservation and emission reduction has become a global consensus. In the construction sector, energy saving and consumption reduction are also becoming increasingly important. As a ubiquitous material in high-rise buildings, ordinary glass has problems of being easily polluted by dust and air and requiring innovative solutions. In this context, TiO2-based self-cleaning glass stands out with its pioneering technology and unique environmental protection characteristics. It meets the needs of automatic cleaning, degradation of surface pollutants, reduction of manual cleaning costs, and alleviation of the burden of environmental pollution. Therefore, promoting the research, development, and application of TiO2-based self-cleaning glass is not only a reflection of scientific and technological progress, but also a key initiative to meet the demand for energy conservation and emission reduction, and to realize sustainable development. This paper systematically reviews the research progress of TiO2-based self-cleaning glass from four aspects:self-cleaning mechanism, development history of TiO2-based self-cleaning glass, preparation process of TiO2-based self-cleaning glass, and modification of TiO2-based films. First, starting from the self-cleaning mechanism, basic principles of TiO2 photocatalytic performance, TiO2 photogenic superhydrophilicity, and the development history of TiO2-based self-cleaning glass at home and abroad are successively elaborated and summarized. The photocatalytic performance of TiO2 under ultraviolet light irradiation is described in detail, which can decompose organic pollutants adhering to the glass surface to realize self-cleaning; At the same time, TiO2 also possesses photo-hyper hydrophilicity. Under the light condition, a thin water film can be formed on the surface rapidly, which further promotes the scouring of pollutants. This not only explains the working principle of TiO2-based self-cleaning glass but also provides a solid theoretical basis for the development of TiO2-based self-cleaning glass at home and abroad. Various enterprises have carried out research and development on TiO2-based self-cleaning glass and put it into production and use in real life. Secondly, the mainstream preparation techniques such as chemical vapor deposition, magnetron sputtering, liquid phase deposition, and sol-gel are discussed, each of which has its unique advantages and applicable scenarios, providing a wealth of choices for the diverse preparation of TiO2-based thin films. As the wide band gap of pure TiO2 determines that it can only be excited by ultraviolet light, which reduces the efficiency of the sunlight utilization. After illumination, the excited electrons and holes are very easy to compound during the migration process. The photogenerated carriers are compounded too fast. The quantum efficiency becomes low, which largely limits the effect of its degradation of pollutants. The modification of pure TiO2 is often used to improve the optical performance. Based on this, this paper reviews the research progress of ion doping (metal ions single doping, non-metal ions single doping, metal ions and non-metal ions co-doping), oxide composite (SiO2, semiconductor oxides), graphene doping, and polymer-assisted modification pathways. The advantages of the composite films over the pure TiO2 films, as well as the reasons for the improvement of photocatalytic and photo-hyper hydrophilic properties, are summarized too. Finally, the research on TiO2-based self-cleaning glass is concluded. The possible challenges of TiO2-based self-cleaning glass are proposed to provide a theoretical basis for its future application. |
