Photocatalyst

Photocatalysis is a promising science for future applications which combines the topics of materials science, nanotechnology, energy research, environmental science, photonics and chemical analysis. The motivation for the current interest in this topic stems from the challenges science and society face from climate change and energy supply. Already, photocatalysis is commercially used to passively degrade pollutants. Another goal is to produce useful chemical products such as H2for the “hydrogen economy” and other solar fuels. It is a simple, renewable, clean and cost effective technology which will play an ever more important role as the science progresses.

Titanium dioxide (TiO2) and zinc oxide (ZnO) have been widely used as a photocatalyst for solar energy conversion and treatment of organic pollutants because of its low toxicity and high photocatalytic efficiency. However, the applicability of ZnO in visible light is limited because of the wide band gap of the material, which results in low efficiency during solar photoconversion.
