Studies of Ion-Beam Modified Hydrogen Evolution Electrodes

The article concentrated on the modifying effects of ion beam mixing, ion implanting and ion sputtering of hydrogen evolution electrodes. It was discovered that the four types of electrodes possessed excellent catalytic activity in both acid and alkaline medium and potential stability in long term electrolysis of water under high current density. Their stability and apolying life-span greatly surpassed those of other electrodes activated by the way of electrodepositing and others. The effects of temperature, and roughness on function of electrodes were also examined. AES and XPS were applied to analyse the surface composition, bond and distribution of concentration varying with depth, and to explain the law of the experiment.
