摘　　要：综述了电沉积析氢电极在析氢反应中的催化机理和研究现状,分析了提高电极催化活性的方法,并对析氢电极的发展趋势进行了展望。非晶、纳米晶以及多元复合电极都表现出了较高的催化活性,但是工业化的析氢电极不仅需要高的催化活性,还需要好的稳定性。高催化活性、高稳定性的非晶态或纳米晶态的多元复合电极将是析氢电极研究的主要方向。Catalytic mechanism and research status of electrodeposited electrode for hydrogen evolution reaction are reviewed in this paper,and the methods of improving the electrode catalytic activity are analyzed and the development trends of the hydrogen electrodes are also discussed.Amorphous,nanocrystalline and multi-composite electrodes show higher catalytic activity.However,industrialization of hydrogen evolution electrodes require not only high catalytic activity but also good stability.Currently,amorphous or nanocrystalline multi-composite electrodes with higher catalytic activity and stability will be the main research topics for the hydrogen evolution electrode.
