Lithium amide and magnesium amide compounds have been studied extensively for hydrogen storage applications. Although these systems have proven to store a significant percentage of hydrogen, there are still some kinetic and cycling obstacles to overcome. Another major concern of amide systems is the possible release of ammonia which can be detrimental to certain types of fuel cells. This study outlines a novel metal vapor reactor which has been used to synthesize hydrogen storage compounds from this promising mixed amide system. The materials generated in this study were characterized using XRD, FTIR, and electron microscopy. The hydrogen storage properties were determined using a TGA and the resulting characteristics were compared to similar mixed amide materials prepared using an alternative method.
