Designing cost-effective materials for photocatalytic water treatment

Water pollution from industry, farming and human sanitation is an acute problem. Biological and organic pollutants, in particular polycyclic aromatic hydrocarbons, pose severe problems. A practical solution to water treatment is photocatalysis, which breaks down molecular pollutants rather than extracting them from water, hence is very effective.

Using a combination of experimental and modelling approaches, we propose:

(i) developing a novel cheap and sustainable method to produce titanium dioxide (TiO2) photocatalysts and

(ii) improving the efficiency of TiO2 photocatalysts for breakdown of aromatic pollutants.

The former will be achieved by using bioinspired methods for the synthesis of TiO2, and the latter by designing molecular surface modifiers to enhance the binding of aromatic pollutants, prior to photocatalytic destruction.
