Ultrasound assisted synthesis of carbon supported Pd nanoparticles toward ethanol electrooxidation

Carbon supported Pd nanoparticles can be synthesized through an ultrasound assisted way. Chloropalladic acid can be reduced by ethylene glycol at room temperature with a commonly used ultrasonic cleaner. No additional surfactants or stabilizers were introduced. The Pd nanoparticles were well dispersed on Vulcan XC-72 carbon. The as-prepared catalysts exhibit superior electrocatalytic performance toward ethanol electrooxidation in alkaline solution. The developed method is simple, convenient, effective and environmentally friendly. (c) 2013 Elsevier B.V. All rights reserved.
