Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light.

Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but these attempts have been of limited success. The present research involves a completely new approach to the problem, which is based on the method used in the heat treatment of sapphire to improve its colour. This approach uses a phenomenon involving the modification of the optical properties to improve its absorption of light.Read moreRead less
