Abstract
A bimetallic oxide Ni<sub>3</sub>(VO<sub>4</sub>)<sub>2</sub> has been synthesized to catalyze the hydrogen storage reaction of MgH<sub>2</sub>. The formation of the Mg<sub>2</sub>Ni alloy and the kinetic modulation of V results in a dehydrogenation temperature of 210 °C. The NiV<sub>2</sub>O<sub>4</sub> intermediate active species is also detected.
