Enhanced catalytic activity of NiM (MÂ =Â Cr, Mo, W) nanoparticles for hydrogen evolution from ammonia borane and hydrazine borane

134Noble-metal-free NiM (M = Cr, Mo, W) NPs have been facilely synthesized via a simple surfactant-aided co-reduction method, which showed a higher catalytic activity than that of pure Ni for the hydrolysis of ammonia borane and hydrazine borane at room temperature.
