We studied the effect of the presence of Me3SiO- group at the surface of SiO2 on the reactivity of Ru nanoparticles towards Water-Gas-Shift.  Ru/SiO2-OSiMe3 exhibits a four times higher methanation rate than Ru/SiO2. The difference in rate of methanation is probably related to the nature of the two support surfaces (Me3SiO- vs. HO-).
