Oxidation of CFU under lean condition (800 ppm) and CO2 reforming of CH4 were carried out using Rh/ZrO2 catalysts with different metal dispersions. It was found that both reactions showed a similar structure-sensitive behavior: The TOF decreased with increasing of Rh dispersion. It is suggested that the rate determining step is dissociative adsorption of CH4 for both reactions, and strong Rh-O bonds in smaller Rh crystallites may lead to a suppression of the dissociative adsorption of CH4 on the Rh surface.
