摘要: A facile method was developed for the controlled synthesis of well-defined Pd nanoparticles and nanowires, with assistance polyhedrin as a growth-directing agent. The concentration plays key role in final morphology. cyclic voltammetry current–time tests demonstrate that samples show vastly superior electrocatalytic properties compared to commercial Pd/C catalysts. Moreover, supported by carbon black or multi-wall nanotube exhibits significantly enhanced activity toward ethanol oxidation, indicating great potential application fuel cells.
