Adsorption of Pt on defective carbon nanotube walls: a DFT approach
نویسندگان
چکیده
In fuel cells, platinum is used as a catalyst to produce atomic hydrogen[1,2]. In order to utilize carbon nanotubes (CNTs) as the Pt carrier electrodes, a sufficiently high binding energy between Pt and the CNT wall is necessary[3]. Pure CNTs have shown to produce low loading amounts of Pt catalyst particles, which is attributed to the weak adsorption of Pt on the CNT walls[4]. However, Pt adsorption has been improved with defective CNT surfaces[5].

Electronic structures of Pt clusters adsorbed on (5,5) single wall carbon nanotube
We present a DFT study for the adsorption of single Pt atom and Pt clusters on graphene surface and carbon nanotube. Adsorption of a Pt atom shows a heavy dependence of binding energy on the graphene curvature. The adsorbed Pt atoms tend to form clusters, than to disperse on the graphene surface. The Pt–Pt bond length and the charge transfer from Pt clusters to the nanotube vary as a function o...
