针对储氢材料存在活化条件苛刻、吸放氢动力学性能差及电化学性能不佳等问题,本文总结了近年来国内外表面处理技术在储氢材料中的研究进展,比较讨论了化学镀表面处理、电镀表面处理、球磨表面处理、氟化表面处理、酸碱盐表面处理、冷轧表面处理和其他表面处理(表面热处理、气相沉积表面处理和磁控溅射表面处理)等对储氢材料表面结构的影响,并探讨不同表面处理方法对储氢材料的活化性能、吸放氢动力学性能、抗气体杂质毒化性能、抗粉化性能、抗氧化性能、循环稳定性及电化学性能等的影响。

In view of the problems of harsh activation condition,poor kinetic performance and poor electrochemical performance of hydrogen storage materials,we summary the research progress of surface treatment technology in hydrogen storage materials at home and abroad in recent years.At the same time,we also compare and discuss the effects of electroless plating surface treatment,electroplating surface treatment,ball milling surface treatment,fluorinated surface treatment,acid-alkali salt surface treatment,cold rolling surface treatment and other surface treatments(surface heat treatment,vapor deposition surface treatment and magnetron sputtering surface treatment)on the surface structure of hydrogen storage materials.The effects of different surface treatment methods on the activation performance,hydrogen absorption and desorption kinetic performance,anti-gas impurity toxicity performance,anti-pulverization performance,oxidation resistance,cycle stability and electrochemical performance of hydrogen storage materials are discussed.
