We investigated carbon dioxide reforming methane over NiCeZrO2 with various a plex agent, such as glycine, citric acid, polyvinyl alcohol, oxalic acid and EDTA. With glycine as the plex agent, the carbon dioxide reforming methane were studied, and effect of amount of plex agent, the ratio of 22Ce to Zr, and the amount of nickel were also investigated. The catalysts were paratively investigated for the carbon dioxide reforming methane in a fixedbed reactor under the conditions of 1 atm, 750 oC, CH4/CO2 =1, and GHSV=53200 mLg1h1. Finally, the optimal reaction condition: with glycine as plex agent, the molar ratio of plex agent to metal was 1, and the molar ratio of Ce/Zr=8:2, 10 Wt.%Ni. The structural and textural properties of the catalysts were characterized by BET, TPR, XRD etc, it is consistent to the experiment results of the catalysts.
