Supported ultrafine NiPt-MoO nanocomposites as highly efficient catalysts for complete dehydrogenation of hydrazine borane

Chemical hydrogen storage materials such as hydrazine borane (HB) have aroused great interest when the tricky hydrogen storage is still a barrier on the way to sustainable hydrogen energy development. Many efforts have been dedicated to the dehydrogenation of HB, but the catalytic performance is still not sufficient enough. Herein, we develop the synthesis of NiPt-MoO x nanoparticles supported on NH 2 functionalized N doped rGO (NiPt-MoO x /NH 2 -N-rGO) via a green and facile method. Unexpectedly, the supported Ni 0.9 Pt 0.1 -MoO x ultrafine nanoparticles (UPs, ∼1.5 nm) show the highest activity by far with 100% selective conversion and a turnover frequency (TOF) of 4412 h −1 at 323 K. A NiPt-MoO x /NH 2 -N-rGO nanocomposite is developed at room temperature, and it has a high dehydrogenation efficiency for hydrazine borane at 323 K.
