摘要：

Core-shell structured nanospheres with mesoporous silica shell and Ni core (denoted as Ni@meso-SiO2) are prepared through a three-step process. Monodispersed Ni precursors are first prepared, and then coated with mesoporous SiO2. Final Ni@meso-SiO2 spheres are obtained after calcination. The products are characterized by X-ray powder diffraction, transmission electron microscopy and N-2 adsorption-desorption methods. These spheres have a high surface area and are well dispersed in water, showing a high catalytic activity with a TOF value of 18.5, and outstanding stability in hydrolytic dehydrogenation of ammonia borane at room temperature.
