Abstract：Efficient and mesoporous nickel-based catalyst was prepared through an “in situ chemical reaction”, and the catalysts were characterized by inductive coupled plasma emission spectrometer (ICP), X-ray diffraction (XRD), transmission electron microscopy (TEM) and N2 adsorption-desorption. The results showed that almost 100% nickel was loaded on SiO2 supports, and this metal-loading method had high utilization ratio of raw materials, which was in line with the concept of “atomic economy”. The obtained catalyst possessed a large amount of meso-pores with size distribution mostly between 10 and 50 nm. When nickel content was as high as 30.2% (mass fraction), the Ni nanoparticles still uniformly dispersed and had a narrow size distribution range of (4.3±0.6) nm. The obtained mesoporous nickel-based catalyst of SiO2@Ni exhibited high catalytic activity and reusability in the preparation of m-phenylene diamine through the hydrogenation of m-dinitrobenzene.
