The Role Of Catalyst Support

1. Fix TiO2, prevent loss, easy to recycle and improve the utilization rate of TiO2;
2. Increase the overall specific surface area of TiO2 photocatalyst;
3. Improve photocatalytic activity. Because some carriers can interact with TiO2, it is beneficial to the separation of E-H+ and increase the adsorption of reactants, and at the same time realize the regeneration of the carrier;
4. Improve light source utilization. If TiO2 is made into a thin film, the number of catalyst particles exposed to light on the catalyst surface increases;
5. The catalyst is fixed with a carrier, which is convenient for making photocatalytic reactors of various shapes.
