Work performed in Richard Walton’s group has been selected as a Research Highlight in the Diamond Light Source Annual Review for 2014-2015. In this work, carried out by PhD student Craig Hiley, the structures of three new metastable ruthenium oxides were determined in a collaborative project between Warwick and sustainable technology company Johnson Matthey. Ruthenium oxides are used in electro-catalysis for water oxidation and reduction, in heterogeneous catalysis, and are also of interest for their electronic and magnetic properties
