Summary: The aim of this project tackles one of the core challenges in the energy sector, i.e. sustainable means of storing solar energy. Due to the variability of sunlight conditions, convert solar energy to chemical energy in a form that allows its use in mobile applications, is a key challenge.
The direct generation of chemical fuels at photoelectrodes is one of the key challenges in large scale exploitation of solar energy. The formation of stable chemical fuels, e.g. H2 and O2 from water, is one of the key and most challenging paths towards large scale energy storage. Oxygen evolution is a complex multi-electron transfer reaction in which IrO2 has been identified as the most active catalyst, although the finding of effective materials remains a formidable challenge. The aim of this project is to develop a new class of materials featuring high-performing nanostructured perovskite catalysts, by a novel synthetic route. Perovskites are transition metal oxides which possess the general chemical formula ABO3, where A is a lanthanide and B is a first-row transition metal. An appealing property of perovskites is the possibility of tuning specific properties such as conductivity, catalytic activity and stability.
