| Abstract: | The relation between catalytic ability for hydrogen evolution reaction and characteristics of nickel-tin alloys prepared by electroplating was investigated.The catalytic ability was found to strongly depend on preparation conditions.Hydrogen overvoltage was drastically decreased with an increase of the width at half height of X-ray diffraction peaks which was related to the tin content.The nickel-arsenide-type structure and the initial high catalytic ability remained unchanged after an 200 hours durability ... |
