Effect of the nature of TiO2 support over the performances of Rh/TiO2 catalysts in the partial oxidation of methane

► Rh supported on TiO2 catalysts are active for methane partial oxidation. ► Anatase-rich support gives better performances than rutile-rich support. ► In anatase-rich support, Rh is highly dispersed and it is highly reduced. ► In rutile-rich support, Rh is poorly dispersed and it is oxidized.
