Effects of carbon supports on Pt nano-cluster catalyst

A first-principles electronic structure calculation is performed to explore stability and electronic structure of Pt13 cluster adsorbed on carbon supports. The stability of Pt13 cluster on carbon nanotube supports has enhanced significantly, compared with that on graphene support. Charge re-distribution among Pt atoms takes place. Electronic structure of carbon supported-Pt cluster exhibits metallic characteristics, similar to a Pt metal surface.
