Ostwald ripening microkinetic simulation of Au clusters on MgO

<p>We investigated the mechanisms and the microkinetics associated with the growth of Au clusters on the Mg(001) surface for clusters size in the range of 1 to 10 atoms.</p><p>The dataset contains thermodynamic data (activations and reactions energies) and raw kinetics data that helped us bring the research conclusions. Upon growth, the number of inter-metallic interactions increases to the detriment of metal-support interactions. We highlighted the odd-even effect induced during the growth of Au clusters. The microkinetic model combined with DFT results provided a unique 'bottom-up approach of the Ostwald sintering of Au clusters on MgO.</p><p>Research results based upon these results are published at https://doi.org/10.1016/j.apsusc.2021.151317<br></p><p><br></p>
