- This is a fundamental study, using both in-situ and ex-situ, multi-element X-ray Absorption Spectroscopy, of deactivation mechanisms in an immobilised version of a homogenous catalyst, widely used in organic transfer hydrogenation reactions. Results were corroborated by catalyst poisoning and kinetic experiments and were critical in terms of commercial catalyst development, in collaboration with Yorkshire Process Technologies (now Apex Molecular Ltd). The work advances mechanistic understanding of changes around the catalytic centre, in both the immobilised and ubiquitous homogenous versions of the catalyst (e.g. doi.org/10.1002/chem.201603825). The approach has been cited in both catalyst (e.g. doi.org/10.1021/acs.chemrev.5b00203) and technique (e.g. doi.org/10.1007/978-3-319-43866-5_27) reviews.
