摘要：NOVELTY - A mesoporous nanoparticle comprises a mesoporous oxidized frame and a metal on surface of the mesoporous oxidized frame. The mesoporous nanoparticle has grain diameter of 80-140 mm and pore aperture of 2.5-3.5 mm. USE - Mesoporous nanoparticle used in catalyst (claimed). ADVANTAGE - The mesoporous nanoparticle has large pore aperture so that large molecules can quickly approach reaction center and reacted product quickly separate from the pore. The preparation of the mesoporous nanoparticle is simple, short in preparation period, easy to carry out, and low in cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the mesoporous nanoparticle, comprising preparing mesoporous nanoparticle precursor from silicon source using surfactant as template agent by gel method; and adding solvent, metal source and water, and carrying out hydrothermal post treatment at 120-150 degrees C to obtain the mesoporous nanoparticle.
