Industrial Chemistry and Water Treatment
Catalytic water purification driven by solar energy: Fundamental understanding and novel materials
C
atalytic decontamination of water by solar energy has attracted substantial interest over the past decades. However, to
develop an efficient photocatalyst for such environmental purification, in particular water treatment still remains a big
challenge, involving Material Science, Chemistry, Engineering and Physics. In particular, there is not a cost-effective way to
deal with large volume of water contaminated by small amount of organic substance or extreme large amount of contaminated
water in suburban region (e.g. oil spill in Mexico Gulf, in China Bohai Sea). Inorganic photocatalysis using solar energy to
mineralize organic contaminants in principal is the potentially best solution to these issues and works in the cost-effective way.
Recently, we preliminarily illustrated the key factors dominating the efficiency of process driven by light irradiation. Following
that, water treatment was carried out in my group which is a challenging topic due to its complexity. In this talk, the mechanism
of the chemical process, involving charge transfer and reaction with oxygen, will be addressed and structured/junction material
development will be presented, resulting into a few times higher activity for textile water treatment and simulated river water
treatment compared with the benchmark photocatalyst P25. Furthermore, a new and facile method to synthesize these active
photocatalysts will be discussed.
