摘要
We show through first-principles calculations that the electronic properties of Pt-4 clusters can be tuned by adsorption on substrates with different electronic valence characters. Pt clusters exhibit a metallic character on gamma-Al2O3(111) and insulator properties on CaZrO3(001). The noted difference indicates the role of the electronic valence states of the substrate atoms that directly bond with Pt.
