摘要
A novel process has been developed to synthesize MgH2 nanoparticles by combining ball milling and thermal hydrogenolysis of di-n-butylmagnesium (C4H9)(2)Mg, denoted as MgBu2. With the aid of mechanical impact, the hydrogenolysis temperature of MgBu2 in heptane and cyclohexane solution was considerably lowered down to 100 degrees C, and the MgH2 nanoparticles with an average particle size of ca. 8.9 nm were obtained without scaffolds. The nano-size effect of the MgH2 nanoparticles causes a notable decrease in the onset dehydrogenation temperature of 225 degrees C and enthalpy of 69.78 kJ mol(-1) center dot H-2. This thermally-assisted milling and hydrogenolysis process may also be extended for synthesizing other nanomaterials.
