A comprehensive study of the effect of the combustion fuel (i.e., glycine and sucrose), ignition source (i.e., furnace and microwave radiation), and nickel content is carried out for the dry reforming of methane (DRM) using La0.6Sr0.4NiyAl1-yO3 (LaSrNiAl) (y = 0.1; 0.2 and 0.3) perovskite-type catalyst precursors synthesized by solution combustion synthesis (SCS). The composition of the catalyst precursor and the combustion fuel rather than the ignition source affected markedly the crystalline phase composition, crystallite size, morphology, specific surface, and reducibility. Those changes are also reflected in the catalytic performance of the SCS-prepared catalyst in the reaction of DRM. The results clearly show that the SCS approach can effectively tune the dry reforming of methane and the reverse water-gas shift reactions by varying the combustion fuels.
