摘要：
Rhodium supported on various metal oxides was studied in the dry reforming reaction using methane and carbon dioxide, in order to reveal the effect of support on the catalytic activity of Rh. The TOF (turnover frequency) based on exposed Rh decreased in the following sequence of support: TiO2 > La2O3 (sic) CeO2 > ZrO2 (sic) MgO (sic) SiO2 (sic) MCM-41 > gamma-Al2O3. The different TOF could be correlated with the stabilized species of Rh atom. It was concluded that the supports influenced the electronic state of Rh atoms, and that Rh metal catalyzed this reaction as a prominent active species.
