A Simple and Controlled Synthesis of Net-like Pd Nanostructure and Their Electrocatalytic Properties toward the Oxidization of Formic Acid

Nanostructured Pd networks were synthesized in high yield through the reduction of Pd (acac) 2 using oleylamine as the solvent, reductant and capping agent. The formation of the network Pd nanostructure is due to oriented attachment among the formed primary particles at high temperature. By adjusting the reaction time, concentration of Pd precursor and reaction temperature, their thickness and interconnectivity can be tuned. The prepared nanostructured Pd networks exhibit efficient electrocatalytic activities toward the oxidation of formic acid in acid media. The enhanced electrocatalytic properties of Pd networks can be attributed to the interconnectivity and presence of a large number of active sites on their surfaces.
