【摘要】 <正>The methanol electro - oxidation in alkaline solution was studied in titanium carried Ni - P and Ni deposit electrodes. Methanol oxidation is enhanced by addition of P atoms into the electrode Ni - P.On the one hand,the phosphor in Ni - P can make the Ni - P deposits fine and fine,and leads to the Ni - P deposits with a high specific surface area,which is conducive for methanol oxidation to carry out at a large current.On the other hand,the weak binding between hydrogen and the Ni - P makes adsorbed hydrogen from methanol dehydrogenation on electrode Ni- P more easily cleaned up and makes electrode Ni - P release fresh electrode surface for adsorption of new methanol molecules.The methanol electro - oxidation on electrodes Ni - P just starts at the potential that coincided with that at which Ni（OH）₂ on the surface of electrodes becomes NiOOH.However, on electrode Ni methanol oxidation start behind the potential at which Ni（OH）₂ is oxidized to NiOOH due to the hinder of strongly- absorbed hydrogen.更多还原
