Perovskite NaCeTi 2O 6 (NCT)-supported Ni catalysts were prepared and examined for the steam reforming of methane (SRM) with a low H 2O/CH 4 ratio (1:1), and their structures were characterized by means of powder XRD, energy dispersive X-ray spectroscopy high resolution TEM, temperature-programmed desorption of CO 2, temperature-programmed reduction with H 2, Ni K-edge/Ce L III-edge X-ray absorption near edge structure spectroscopy and extended X-ray absorption fine structure A 4wt% Ni/NCT catalyst exhibited higher activity than 4wt% Ni/TiO 2, Ni/(CeO 2+TiO 2), and Ni/Ce 2O 3 catalysts for SRM reactions at 973K, and better resistance to carbon deposition was observed on 4wt% Ni/NCT compared to 4wt% Ni/CeO 2. It is suggested that the characteristic performance of the Ni/NCT catalysts for the SRM reactions are related to the basic character and oxygen conducting behavior of NCT to control the balance of CH 4 decomposition and carbon gasification with steam on the surfaces of the Ni/NCT catalysts.
