During my PhD, we applied DFT to study energetics and kinetics of small molecule adsorption on catalytically active metal nanoparticles, which were of interest to the Johnson Matthey company. We calculated properties of a series of platinum nanoparticles of up to and exceeding 10000 atoms, to address the question of how oxygen binding and dissociation is affected by the size and distribution of unique binding sites [1]. In order to perform these very large DFT calculations on metals, a large part of the project was to develop methodology for calculating density matrices with fractional occupancy distributions without diagonalization [2].

Working closely with the Nellist group of Oxford Materials, we were given the precise coordinates of Pt atoms, in real-world catalyst nanoparticles using cutting-edge STEM experiments, which we were able to simulate using DFT and to predict and influence further experiments through careful analysis and comparison with model calculations [3].
