The network's two research goals can be summarised as follows. The first goal is to devise a tandem cell which can convert solar energy to chemical energy with an efficiency of 10% or more, using a new nanostructured metaloxide material, and based on an atomic scale understanding of the mechanism of photooxidation of water on metaloxide surfaces, this step being the crucial step. The second goal is to find the best possible hydrogen storage hydrogen material for cheap on-board storage in automobiles (> 5wt%, reversible), by determining experimentally and theoretically what constitutes a good catalyst and what makes the material (and its combination with a catalyst) reversible, by investigating well known and relatively unexplored complex metal hydrides.
