Titanium dioxide TiO2 is widely utilized as a catalyst in various chemical reactions. having the ability to accelerate them without being depleted. This advantageous property allows for its reuse in multiple instances. Specifically. TiO2 shows great efficacy in photocatalysis. expediting light-induced reactions. Upon exposure to UV light. the absorption of photons by TiO2 induces the excitement of electrons and the formation of electron-hole pairs. These accelerated redox reactions can be harnessed to eliminate harmful substances or produce beneficial compounds. Some typical uses for TiO2 as a catalyst include: 1 Harnessing sunlight to decompose water into hydrogen and oxygen for potential environmental-friendly hydrogen fuel production; 2 Amplifying the decomposition rate of organic pollutants through UV irradiation; 3 Using TiO2 coatings on outdoor building materials for their inherent self-cleaning properties by oxidizing and flushing away dust. pollutants. and other organic matter; and 4 Utilizing TiO2 in dye-sensitized solar cells to convert solar energy into electricity. To sum it up. titanium dioxide catalysts are highly effective in accelerating photochemical reactions without being consumed. making them an important tool in numerous applications.
