The Vision: 20 Years Later

Our group visualizes a big change in the future of photocatalysis.

Our prototype: Applying TiO2 on tiles which can be used on building walls

First, the surface area of TiO2 should be increased to absorb more photoenergy and to enhance efficiency by allowing visible-light to activate the catalyst instead of ultraviolet.  Second, we need to reduce the band-gap energy so that visible light can be used .  Finally, effective methods need to be developed to prevent recombination of e-/h+ pairs.  With these changes, TiO2 would be able to activate under visible light efficiently.

With these changes, we will be able to use TiO2 photocatalysts for many uses, as displayed in the following diagram. 

Part 1: Increasing Contact Surface

Part 2: Reducing the Band-Gap Energy

Part 3: Preventing Recombination
