By catalyzing the hydrolysis of dimethylamine-borane on MoS2 nanosheets, hydrogen evolution can be achieved more efficiently. Co/MoS2 is found to be more efficient in producing hydrogen, utilizing hydrogen atoms in water.
Since dimethylamine-borane ($ 463/kg) is much cheaper than ammonia borane ($ 13,921/kg), the hydrolysis of dimethylamine-borane catalyzed by transition metal nanocatalysts has long been proposed as a viable opportunity for hydrogen evolution, but it often required noble metals nanocomposites, such as Pt, Rh and Ru. Herein, we first report the ultrafine non-noble metal nanoparticles supported on MoS2 nanosheet (including Fe/MoS2, Co/MoS2, Ni/MoS2 and Cu/MoS2) for the H-2 evolution from hydrolysis of dimethyl amine-borane (DMAB). Among them, Co/MoS2 is found to be more efficient than others for the H-2 evolution, with the TOF of 374 mol((H2)).mol(cat)(-1).h(-1). Kinetic isotopic experiment and the tandem reaction have confirmed that H-2 evolution by using H atoms in water.
