Photoelectrochemical purification of water

Objective

Water purification is a key issue of the 21st century. Slurries or thin films of illuminated titanium dioxide have been shown to provide a means for photo oxidising organic pollutants in water. The project aims at working out the basic concepts and studying the reaction mechanisms for drinking and waste water purification by photo electrochemical means, with the ultimate aim to power these systems with solar energy. More specifically, the two main objectives of the project are the elaboration of efficient, inexpensive photo electrode materials in thin-layer form, and the determination of the chemical-chemical mechanisms leading to oxidative degradation of pollutants and micro organisms. Inexpensive oxide-based photo anodes in thin-layer form and large surface area will be prepared by a number of different techniques. These films will be characterised by physical and photo electrochemical means, and their performance for the photo oxidation of model organic pollutants or micro organisms will be assessed quantitatively in laboratory-scale test reactors.
