A kind of Ni containing mesoporous silica. Ni-KIT-6, was prepared by a one-spot co-assembly method, in which Ni species were highly dispersed into the pore walls during the self-assembly synthesis of the mesoporous silica. Compared with the catalyst prepared by conventional impregnation method. Ni-KIT-6 demonstrates extremely smaller Ni particles on the support and stronger interaction of Ni with silica matrix. As a result, it exhibits high catalytic activity and selectivity, and more importantly, good coke-resistant performance for the catalytic reaction of methane reforming with carbon dioxide.
