Bi-reforming (combined steam and CO2 reforming) of methane was studied over platinum (0.5, 2 wt. %) or palladium (0.5, 2 wt. %) and/or nickel (8 wt. %) and magnesium (8 wt. %) immobilized onto a ceria-zirconia support. XRD patterns demonstrated that the support was a cubic fluorite structure and Ni and Mg were immobilized onto it. Temperature-programmed reduction showed that addition of Pt or Pd substantially decreased the reduction temperature. CO2 desorption studies indicated that the metals had an impact on the basicity of the catalysts.  Bi-reforming studies also showed that addition of Pt or Pd improved the H2:CO ratio.
