6 Mg(BH4)2-4FGi composite decompose below 170 °C.
Numerous nanoscale spots formed in 3 Mg(BH4)2–3LiBH4-4FGi composite.
Synergetic modification of FGi and LiBH4 could suppress the B2H6 released from Mg(BH4)2.
Synergetic effect of FGi and LiBH4 can significantly improve the dehydrogenation kinetics of Mg(BH4)2.
