研究析氢活性电极对燃料电池、氢能和氯碱等电化学工业有重要实际意义,对查明电催化过程和析氢机理有重要理论价值.提高析氢阴极的活性和稳定性是电化学领域中最引人注目的课题之一.国内外研究十分活跃.作者应用离子束技术得到高活性析氢阴极,开辟了离子束化学的新方向.近来作者采用Mo、W和C离子束对Ni、Mo和W组成的表面合金进行改性,得到一系列在酸性介质中稳定的高活性新型析氢电极,本文报道这些电极在碱性介质中的行为.
Studying the hydrogen evolution electrode has important practical significance for the electrochemical industry such as fuel cell, hydrogen energy and chlor-alkali, and has important theoretical value for identifying the electrocatalytic process and hydrogen evolution mechanism.Improve the activity and stability of the hydrogen evolution cathode is the most cited in the field of electrochemistry People are one of the subjects of attention.Studies are very active at home and abroad.The author applied ion beam technology to obtain highly active hydrogen evolution cathode, opened up a new direction of ion beam chemistry.Recently the authors using Mo, W and C ion beam Ni, Mo and W composition Surface modification of the alloy to obtain a series of highly active new hydrogen evolution electrodes that are stable in acidic media. The behavior of these electrodes in alkaline media is reported in this paper.
