Abstract |
Polymer electrolyte membrane fuel cells (PEMFCs) have high efficiency and environment-friendly compared other cells. Palladium catalysts have significant properties at ethanol oxidation reaction of anode fuel oxidation reaction in PEMFCs. It is correlated the transition metal electronic structure and well-known forms of volcano curve. In addition, controlling catalysts shape and composition at nanoscale enhanced efficiency of palladium catalysis. shape effect is controlled particles shape and crystalline that changes surface area and energy, and composition effect changes electronic structure and interaction of a reactant in the electrode reaction to catalysts. These control effects expect improvement of palladium catalysis.
Herein, palladium nanoparticles and sulfidation of pre-formed palladium nanoparticles using a facile synthesis method, measured different shapes and electrocatalysis properties for ethanol oxidation reaction. |
