The Ni/Al2O3-MgO nanocatalyst with Al/Mg ratio of 1.5 was prepared successfully using sonochemistry method and shown high activity and stability in dry reforming of methane. XRD, BET, FESEM, TEM and EDAX-dot mapping techniques have been used for nanocatalyst characterization. XRD analysis confirmed the formation of MgO and NiO cubic phases. According to the FESEM micrographs, nanostructure grains with uniform surface size distribution have been observed in of the synthesized nanocatalyst. The TEM micrographs showed that ultrasound-assisted preparation method induced uniform morphology without agglomeration of particles. The activity of synthesized nanocatalyst could reach thermodynamic equilibrium conversions and H-2/CO ratios. (C) 2013 The Korean Society of Industrial and Engineering Chemistry.
