Abstract: Ordered mesoporous carbon nanofibers were prepared by combining the soft template synthesis method of mesoporous carbons with the confinement of channels of anode alumina membranes. The ordered mesoporous carbon nanofibers as supports for loading Pt nanoparticles were obtained using a noncovalent method and ethylene glycol reduction. The results indicate that the mild functionalization method is beneficial for conservation of mesostructure of supports and distribution of Pt nanoparticles. Moreover, the condition of reduction is very important for the load of Pt nanoparticles. The electrochemical properties were studied by cyclic voltammogram and the results show that the Pt-catalysts possess excellent methanol electrocatalytic activity and stability.
