Buckyball-, carbon nanotube-, graphite-, and graphene-enhanced dehydrogenation of lithium aluminum hydride

Compared to C60, carbon nanotubes, and graphite, graphene more effectively lowers the dehydrogenation temperature and improves the dehydrogenation kinetics of LiAlH4. With 15 wt% graphene incorporation, the initial hydrogen release temperature is ∼80 °C (60 °C lower than that of pristine LiAlH4).
