We employed "evaporation" process for the synthesis of LiNH2 (Li-amides) as a candidate of advanced hydrogen storage materials. In the process, the metallic Li is first heated under vacuum to yield the evaporated Li film onto a metal substrate, and then, the Li film was nitrogenated and hydrogenated to prepare the LiNH2 film. It is found that hydrogen desorption temperature of the film is lower than that of conventional powder-shaped samples, implying that non-conventional synthesis processes, including "evaporation" demonstrated in the present study, are effective to improve hydrogen absorbing/desorbing properties of complex hydrides.
