Hydrazine　borane　(HB)　has　been　considered　as　a　promising　hydrogen　storage　material　due　to　its　high　hydrogen　content　and　stability　at　room　temperature.　For　the　first　time,　a　facile　wet-chemical　method　is　developed　to　synthesize　amorphous/low　crystalline　noble-metal-free　Ni-MoOx/BN　composite　as　a　low-cost　and　high-efficient　catalyst　for　hydrogen　generation　from　HB　decomposition.　The　as-prepared　Ni-MoOx/BN　hybrid　exerts　100%　selective　conversion　and　can　catalyze　HB　complete　decomposition　within　5　min,　corresponding　to　a　turnover　frequency　(TOF)　value　of　600.0　h(-1)　at　323　K.　The　excellent　catalytic　activity　may　be　attributed　to　the　good　dispersion,　uniform　particle　size　(approximate　to　2.6　nm),　and　electronic　effect　between　nanoparticles　(NPs)　and　support　material.　On　further　reducing　the　dosage　of　Ni,　the　catalyst　still　exhibits　supreme　performance,　with　the　TOF　value　of　2370　h(-1)　(n(Ni)　=　0.008　mmol)　at　323　K,　which　is　the　highest　one　among　all　the　reported　catalysts　for　full　decomposition　of　HB.　Thus,　the　excellent　catalytic　results　provide　more　possibilities　for　the　effective　application　of　HB　as　a　promising　hydrogen　storage　material.
