SnO2 nanospheres supported Pd catalyst with enhanced performance for formic acid oxidation

SnO 2 nanospheres were employed as the support material for Pd catalyst. The as-prepared Pd/SnO 2 catalyst exhibited remarkably improved electrocatalytic activity and stability towards formic acid oxidation , in comparison with that of the Vulcan XC-72 carbon black and the commercial SnO 2 nanopowder supported Pd catalyst. The enhanced catalytic performance may arise from the unique structure and surface properties of the SnO 2 nanospheres, which process extraordinary promotional effect on Pd catalyst.
