| Abstract: | Highly dispersed Ru nanoparticles on mesoporous TiO2 have been synthesized by a one-step ultrasound assisted polyol reduction procedure. The catalysts have been characterized by XRD, TEM and HR-TEM, EDX, BET and TPR methods. It has been demonstrated that the sonochemical method reduces the Ru+3 ions creating a narrow size distribution of metallic nanoparticles deposited on the mesoporous support without damaging its pore structure. The nanoparticles of Ru are highly dispersed and stable because of their incorporation into the mesopores, and the strong metal-support interaction. The catalytic properties of Ru/TiO2(MSP) have been tested in the partial oxidation of methane, and high activity and selectivity towards CO and H2 have been demonstrated. |
