铝氢化物热稳定性研究进展
Research Progress on Thermal Stability of Aluminum Hydrides
摘要
Abstract
Aluminum hydride is regarded as an important candidate material for solid hydrogen storage be-cause of its high theoretical hydrogen storage density.However,in practical applications,such materials still face many challenges,including slow dehydrogenation kinetics,high dehydrogenation temperature due to high thermal stability,and poor cycle performance,which seriously restrict their commercialization process.The characteristics and mechanism of dehydrogenation of aluminum hydride were reviewed,and the thermal stability control strategies such as surface modification,doping modification and synthesis of multicomponent compound hydride system were discussed.The results showed that the surface of the materials can be changed,the grain aggregation can be inhibited,and the kinetics of dehydrogenation can be improved.Catalytic doping of metals and compounds can significantly improve the hydrogen storage performance by forming amorphous in-situ active substances.By reconstructing the reaction path and introducing the multiphase instability effect,the multi-com-ponent composite system can effectively ensure the actual hydrogen storage capacity while improving the kinetic and thermodynamic properties.In the future,it is necessary to break through the single modification strategy and focus on the development of multi-directional collaborative optimization path,so as to lay a solid theoretical and technical foundation for aluminum hydride from laboratory research to large-scale application.关键词
