A facile method to synthesize Pt nanoparticles on the electrospun SnO2 fiber matrix is presented. Precursors contained tin chloride pentahydrate, hexachloroplatinic acid, polyacrylonitrile, and N,N-dimethylformamide were electrospun and subsequently calcinations was carried out at 500 degrees C for 4 h. It is shown that Pt nanoparticles were grown on SnO2 fiber matrix without any formation of PtO. Pt nanoparticles size was in the range of 6-32 nm, by adjusting the concentration of polyacrylonitrile. The electrochemically active surface area of Pt/SnO2 fibers was found to be very competitive compared to the commercially available electrocatalyst. This work demonstrates that Pt/SnO2 fibers can be generated by a facile electrospinning process. Crown Copyright (C) 2013 Published by Elsevier B.V. All rights reserved.
