Mesoporous SiO₂-Supported Pt Nanoparticles for Catalytic Application

SiO 2 nanoparticles have been synthesized by combining Stober’s method and nonsurfactant process. The diameters and pore sizes can be controlled by altering the template and its concentration. Mesoporous SiO 2 obtained this way has extremely large surface area compared with most oxide supports, which benefits the catalytic performance. Pt nanoparticles were in situ grown on and in mesoporous SiO 2 nanoparticles with low amount of the metal and...
