Abstract – Perovskite-supported Ni catalysts were prepared by Atomic Layer Deposition for use in CO2 and steam reforming of methane. Thin films of CaTiO3 were grown on MgAl2O4 and used as the support. These catalysts were found to be self-regenerating following redox cycling. Activities for the ALD-prepared catalysts were higher than that observed on Ni/MgAl2O4 in both steam reforming and dry reforming. More importantly, the perovskite-supported catalysts showed minimal coking, even upon exposure to dry methane at high temperatures.
