概要:

The supercritical carbon dioxide (scCO2) for the impregnation and deposition of metal nanoparticles are effective for uniformly decorating and impregnating porous materials. In this work, Cu-Ru bimetallic nanoparticles were successfully immobilized in the mesopores of hierarchical porous SiO2 by using scCO2-acetone solution. STEM-EDX mapping measurements demonstrated that Cu and Ru atoms were homogeneously scattered in mesopores of hierarchical porous SiO2. The resulting … Cu-Ru@SiO2 exhibited high activity. The catalytic activity of bimetallic Cu-Ru@SiO2 for CO oxidation was higher than that of monometallic Cu@SiO2, Ru@SiO2 and Rh@SiO2. 続きを見る
