TiO2 has been widely studied as a photocatalyst for various solar environmental and energy application. Its photocatalytic performance is largely related to its optical and structural properties. For example, its UV-only optical absorption limits its main photocatalytic applications in the UV region and its low overall photocatalytic efficiency. Therefore, much effort has been devoted to improve its optical absorption properties. In this work, we present various strategies in the direction of manipulating its optical properties towards enhanced photocatalytic performances. Representative work from our group will be given to discuss the advantage and disadvantages of those strategies. Discussion of future effort will be proposed as well.
