الملخص | Development of a highly efficient, nickel-based nano-catalyst in the carbon dioxide reformation of methane is reported. The alumina supported Ni-based catalyst with a metal loading of 5wt% was prepared via solution combustion synthesis (SCS) method and conventional wetness impregnation method. Compared to that of conventional Ni(I) catalyst, the Ni(SCS) catalyst exhibited high activity for methane conversion and superior selectivity for H 2 and CO production during dry reforming of methane. This difference in the catalytical performances of both catalysts during the dry reformation of methane was attributed to difference in morphology and chemical structures of the catalysts. The HAADF-EDS analysis of the Ni(SCS)catalyst revealed Ni was homogeneously distributed over the substrate with an average particle size of 7±2.31nm. Additionally, SAED patterns suggested that nickel was mainly observed in the NiAl 2 O 4 phase. These findings were affirmed by the XRD analysis. By contrast the Ni(I) catalyst revealed the presence of free NiO species only. |
