The results of the present DFT study show that ZnO vacancies on ZnO(10-10) provide a competitive mechanism for stabilizing the Pd single atom species at elevated temperatures. This prediction suggests a novel form of metal-support interaction where metal atoms get incorporated into the support and modify its catalytic behavior.
