Research progress on supported ammonia borane hydrolysis catalysts for hydrogen production

氨硼烷(AB)作为一种液相储氢材料,因其氢含量高而倍受关注。然而,AB水解的速率缓慢且催化机理未决影响了其大规模应用;因此,研究开发高效AB水解制氢催化剂具有重要意义。综述了负载型AB水解制氢催化剂的研究进展,包括活性中心材料,以及碳材料、金属氧化物、金属氢氧化物、过渡金属碳化物、二维过渡金属碳/氮化物、金属有机框架、金属氮化物和共价有机框架等载体材料;讨论了AB水解的反应机理,并对AB水解制氢的未来发展进行了展望。

Ammonia borane(AB) is a liquid-phase hydrogen storage material that has gained significant attention due to its high hydrogen content.However,the slow rate and the uncertain catalytic mechanism of AB hydrolysis have hindered its large-scale application.Therefore,the development of efficient supported catalysts for AB hydrolysis to generate hydrogen is of great importance.The research progress on catalysts for hydrolysis of AB was reviewed,focusing on active center materials and carrier materials such as carbon materials,metal oxides,metal hydroxides,transition metal carbides,two-dimensional transition metal carbonide/nitrides,metal-organic frameworks,metal nitrides,and covalent organic frameworks.The reaction mechanism of AB hydrolysis was discussed,and the future development of AB hydrolysis for hydrogen production was also prospected.
