AbstractCH 4/CO 2 reforming over La 2NiO 4 and 10%NiO/CeO 2-La 2O 3 catalysts under the condition of supersonic jet expansion was studied via direct monitoring of the reactants and products using the sensitive technique of cavity ring-down spectroscopy. Vibration-rotational absorption lines of CH 4, H 2O, CO 2 and CO molecules were recorded in the near infrared spectral region. Our results indicated that La 2NiO 4 is superior to 10%NiO/CeO 2-La 2O 3 in performance. In addition, we observed enhanced reverse-water-gas-shift reaction at augmented reaction temperature. The formation of reaction intermediates was also investigated by means of time-of-flight mass spectrometry and there was the detection of CH x +, OH + and H + species. © 2007 Elsevier B.V.
