Abstract
Pd electrocatalysts supported on antimony tin oxide and Vulcan XC-72 were both synthesized via a modified sodium borohydride reduction method. The catalysts were characterized by means of powder X-ray diffraction and cyclic voltammetry. Linear sweep voltammetry, open circuit potential curves and chronoamperometry were employed to evaluate the activities of the catalysts. The results show the particle size of Pd in the Pd electrocatalysts supported on antimony tin oxide catalyst is about 2.5 nm, which is smaller than that of the Pd electrocatalysts supported on Vulcan XC-72 (about 6.3 nm), and the surface area of the Pd electrocatalysts supported on antimony tin oxide electrode is larger than that of the Pd electrocatalysts supported on Vulcan XC-72 electrode. The Pd catalyst supported on antimony tin oxide shows superior performance to the catalyst supported on Vulcan XC-72.
