We're a chemistry research group working across the areas of solid-state chemistry and heterogeneous catalysis, with the overarching goal of developing materials and processes that will help enable society’s transition to a sustainable global energy system. We have expertise in the synthesis, characterisation and understanding of novel inorganic systems, principally metal-nitrogen-hydrogen (M-N-H) materials.
In all our work we seek to understand the chemistry which underpins the desired function of a material. We do this using a variety of structural and spectroscopic probes, with a particular emphasis on in situ or in operando techniques, where we can examine the material in its active state. We also aim to be engaged in projects which range from fundamental science to technology demonstration.

Ammonia synthesis catalysis
We've recently collected some in-situ synchrotron X-ray diffraction data for the reactions of lithium hydride and lithium hydride - transition metal composites with nitrogen gas as part of our efforts to understand the ammonia synthesis behaviour of these catalysts. Take a look at the GIFs Ezri has been putting together to explore these reactions. Each GIF shows a particular Bragg peak of interest in the sample.
