Research Progress of Hydrolytic Noble Metal Catalyst for Hydrogen Production from Ammonia Borane

氢能很有希望成为化石能源的替代品,但氢能的储存和运输还存在诸多问题。氨硼烷(NH_(3)BH_(3),AB)性质稳定,储氢量高达19.6wt%,是优秀的固态储氢材料,在室温下合适的催化剂可高效、安全、稳定地催化氨硼烷水解产氢。本文综述了近几年氨硼烷水解催化剂中无载体、有载体、MOFs衍生物的贵金属催化剂的催化活性、表观活化能、循环稳定性等,分析了催化剂活性提升的原因,展望了未来氨硼烷产氢催化剂的主要研究方向。

Hydrogen is a promising alternative to fossil fuels,However,there are still many problems in the storage and transportation of hydrogen energy.Ammonia Borane(NH_(3)BH_(3),AB)is a stable solid hydrogen storage material with hydrogen storage capacity up to 19.6wt%.At room temperature,the suitable catalyst can efficiently,safely and stably catalyze the hydrolysis of ammonia borane to hydrogen production.In this paper,catalytic activity,apparent activation energy and cycle stability of the unsupported,supported and MOFs derived noble metal catalysts for hydrogen production from AB hydrolysis in recent years are reviewed.The reason of catalyst activity increase was analyzed,and the main research direction of ammonia borane hydrogen production catalyst was prospected in the future.
