Metal species with different size (single atoms, nanoclusters, and nanoparticles) show different alytic behavior for various heterogeneous alytic reactions. It has been shown in the literature that many factors including the particle size, shape, chemical composition, metal–support interaction, and metal–reactant/solvent interaction can have significant influences on the alytic
