Through literature research and experimental methods, the understanding of the hydrogen storage mechanism and development direction of NaAlH4 has been deepened. In the experimental process, NaAlH4 powder was prepared into nano-powder by high temperature plasma ball milling, and then the modified powder was prepared by solution impregnation method and solid ball milling method. The physical properties and hydrogen storage performance were tested, and the influence of catalytic composite modification on the hydrogen storage properties of NaAlH4 was discussed. The results showed that the hydrogen storage performance of NaAlH4 powder was significantly improved after nanoconfinement and catalytic composite modification, and some factors that limited the hydrogen storage performance were also found. The results of this study have reference significance for further improving the hydrogen storage properties of NaAlH4 and promoting the development of hydrogen energy technology.Keywords: Hydrogen storage, NaAlH4, Nanoconfinement, Catalytic composite modification, Hydrogen energy technology
