摘　　要：氨硼烷储氢量大,成为储氢材料研究热点。金属催化剂可以显著降低氨硼烷热解温度,提高水解放氢速度,是影响氨硼烷放氢的关键因素。综述了目前所采用或正在研究的催化氨硼烷放氢金属催化剂,如贵金属催化剂、贵金属与非贵金属复合的催化剂、非贵金属催化剂等,比较了各种催化剂的优缺点,总结了近年来金属催化氨硼烷放氢机理的研究结果。对已取得的研究成果进行了评价,并指出其相关发展趋势。Ammonia borane has been considered as a promising candidate material for hydrogen storage due to its very large hydrogen storage. The pyrolysis temperature of ammonia broane can be lower and the rate of hydrolysis can be faster with metal catalysts, the key factor influencing the hydrogen generation of ammnia borane. The metal catalysts catalyzing ammnia borane to generate hydrogen most used or under research such as noble metal catalysts, the composite catalysts of noble and nonoble metals and nonoble metal catalysts were reviewed. The advantages and disadvantages of the catalysts were compared. The research results of the reactions mechanisms were summarized. The obtained research results were evaluated, and the development trend of the hydrogen storage technology was pointed out.
