It is highly desirable to develop a technology with a high-density hydrogen generation at room temperature in the field of hydrogen energy. Ether solvents are proposed to improve the hydrogen generation properties of the reaction between LiAlH4 and NH4Cl (LiAlH4- NH4Cl) in this paper. The reactions in diethyl ether (LiAlH4-NH4Cl-Et2O), tetrahydrofuran (LiAlH4-NH4Cl-THF) and dimethoxyethane (LiAlH4-NH4Cl-DME) all exhibit good hydrogen generation performances with the H-2 yields of about 5.50, 5.52 and 5.31 wt% respectively at 25 degrees C, which are obviously superior to the pyrolysis behaviors at high temperature of 170 degrees C required in hydrogen generation reaction of LiAlH4 and NH4Cl. It is found that the higher the LiAlH4 solubility in solvents, the faster the initial hydrogen generation kinetics; and the higher the by-product LiCl solubility in solvents, the shorter the reaction time. In addition, new compounds with a similar molecular formula HAlNH center dot 0.25Ether (the Ether is Et2O, THF or DME) are found in the solid by-products.
