Abstract

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 SrNiO 3 and CeNiO 3 perovskites for syngas production via DRM. CeNiO 3 exhibits a higher specific surface area, pore volume, number of reducible species, and nickel dispersion when compared to SrNiO 3 . The catalytic activity results demonstrate higher CH 4 (54.3%) and CO 2 (64.8%) conversions for CeNiO 3 , compared to 22% (CH 4 conversion) and 34.7% (CO 2 conversion) for SrNiO 3 . 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 (SrNiO 3 and CeNiO 3 ) but SrNiO 3 showed more deactivation than CeNiO 3 , as demonstrated by deactivation factors. The catalyst deactivation is mainly attributed to carbon deposition and these findings are verified by characterizing the spent catalysts.
