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. © 2008 Elsevier B.V. All rights reserved.
