摘要: Well-dispersed palladium nanoparticles on the surface of three-quarter-sphere-like £-AlOOH were prepared by an efficient, low-cost and facile reductive process that utilizes 0.01mol/L NaBH4 solution. The morphology, structure elemental composition this Pd/£-AlOOH composite characterized field emission scanning electron microscopy (FESEM), transmission (TEM), highresolution (HRTEM), X-ray diffraction (XRD) energy-dispersive spectroscopy (EDS). results showed Pd homogeneously dispersed their size distributed from 6 to 8.5nm. Electrochemical performance Pd/ toward methanol in alkaline solution was examined using cyclic voltammetry (CV) chronoamperometric techniques. indicated novel had excellent electro-catalytic activity long-term stability.
