Nickel nanoparticles highly dispersed with an ordered distribution in MCM-41 matrix as an efficient catalyst for hydrodechlorination of chlorobenzene

Abstract Ni/MCM-41 materials in which highly dispersed nickel nanoparticles with an ordered distribution were successfully prepared by crystal lattice locating method. The synthesized samples were characterized by XRF, XRD, XPS, HRTEM, and N 2 adsorption–desorption isotherm techniques. The results suggest that the materials possess highly ordered hexagonal mesostructure of MCM-41 and the highly dispersed nickel nanoparticles with a uniform size smaller than 20 nm are in an ordered configuration in MCM-41 matrix. The materials with high specific surface area, large pore volume, and big pore diameter exhibit an excellent catalytic performance in hydrodechlorination of chlorobenzene.
