The development of a transition-metal-based catalyst with concomitant high activity and stability due to its distinguishing characteristics, yielding an abundance of active sites, is considered to be the bottleneck for the dry reforming of methane (DRM). This work presents the catalytic activity and durability of SrNiO₃ and CeNiO₃ perovskites for syngas production via DRM. CeNiO₃ exhibits a higher specific surface area, pore volume, number of reducible species, and nickel dispersion when compared to SrNiO₃. The catalytic activity results demonstrate higher CH₄ (54.3%) and CO₂ (64.8%) conversions for CeNiO₃, compared to 22% (CH₄ conversion) and 34.7% (CO₂ conversion) for SrNiO₃. The decrease in catalytic activity after replacing cerium with strontium is attributed to a decrease in specific surface area and pore volume, and nickel active sites covered with strontium carbonate. The stability results reveal the deactivation of both the catalysts (SrNiO₃ and CeNiO₃) but SrNiO₃ showed more deactivation than CeNiO₃, as demonstrated by deactivation factors. The catalyst deactivation is mainly attributed to carbon deposition and these findings are verified by characterizing the spent catalysts.
