Abstract

Steam reforming of methane has been carried out aimed at the development of new and highly active catalysts for H₂ production. The catalytic properties of Ni catalysts supported on various supports have been investigated in connection with characterization results obtained from XRD, H₂ chemisorption, TPR and CO₂-TPD. Among the catalysts examined, Ni/Ce-ZrO₂ exhibited the best activity and stability. The remarkable catalytic performance is interpreted as a combined result of high oxygen storage capacity of ceria in Ce-ZrO₂, strong interaction between Ni and Ce-ZrO₂, basic property of the catalyst and rather high capability of H₂ uptake.
