Effect of nickel incorporation into hydrotalcite-based catalyst systems for dry reforming of methane

Effect of nickel incorporation into hydrotalcite-based catalyst systems for dry reforming of methane The reaction of CO2 methane reforming was tested over hydrotalcite-based catalysts containing nickel. The nickel species were introduced into the catalysts at the coprecipitation stage (HTNi) or postsynthesis (HTexNi). Characterization of the catalysts by elemental analysis, X-ray diffraction (XRD), H2 temperature-programmed reduction (TPR), diffuse-reflectance (DR) ultraviolet–visible (UV–Vis), low-temperature N2 sorption, and Fourier-transform infrared (FTIR) experiments confirmed successful introduction of nickel species into the hydrotalcite structure and onto external surfaces of crystallites. Both synthesized catalysts were active in the reaction of dry methane reforming at 550 °C. Higher values of CH4 and CO2 conversions were obtained for the coprecipitated sample (HTNi). However, higher catalytic activity per gram of active material was shown by the HTexNi sample, indicating that the method of preparation of hydrotalcite-based catalysts strongly influenced their catalytic performance. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

The reaction of CO2 methane reforming was tested over hydrotalcite-based catalysts containing nickel. The nickel species were introduced into the catalysts at the coprecipitation stage (HTNi) or postsynthesis (HTexNi). Characterization of the catalysts by elemental analysis, X-ray diffraction (XRD), H2 temperature-programmed reduction (TPR), diffuse-reflectance (DR) ultraviolet–visible (UV–Vis), low-temperature N2 sorption, and Fourier-transform infrared (FTIR) experiments confirmed successful introduction of nickel species into the hydrotalcite structure and onto external surfaces of crystallites. Both synthesized catalysts were active in the reaction of dry methane reforming at 550 °C. Higher values of CH4 and CO2 conversions were obtained for the coprecipitated sample (HTNi). However, higher catalytic activity per gram of active material was shown by the HTexNi sample, indicating that the method of preparation of hydrotalcite-based catalysts strongly influenced their catalytic performance.
