摘要：

The size-controlled synthesis and catalytic performance of Pt nanoparticles in micro- and mesoporous silica prepared using supercritical fluids was reported. Pt precursors dissolved in supercritical CO2 with acetone, were loaded on the FSM-16, followed by reduction in flowing H2. Investigation of the influence of particle size on catalytic activity indicated that smaller Pt nanoparticles catalyze the CO oxidation reaction more efficiently.
