Syngas production via methane dry reforming: A novel application of SmCoO3 perovskite catalyst

Supercritical fluid-assisted modification combined with the resynthesis of SmCoO3 as an effective tool to enhance the long-term performance of SmCoO3-derived catalysts for the dry reforming of methane to syngas

“…Previous studies of the DRM activity of SmCoO 3 prepared by sol-gel techniques [28][29][30] showed that the increase in the syngas yield occurs upon heating to 800 °C, and pre-reduction by H 2 Scheme 1 Designation of the samples studied in this work. ‡ In the case of SmCo, theoretical pattern from previously reported structure (CCDC 2099934) can be additionally applied to prove single-phase state of the isolated sample.…”

“…derived from corresponding LnMO 3 perovskites attract considerable attention. 9,[12][13][14][23][24][25][26][27][28][29][30] The main advantages of such catalysts are relatively low cost combined with the capability to achieve considerable activity. Concerning the design of stable catalysts, Co/Ln 2 O 3 composites and corresponding LnCoO 3 generally look prospective due to high coking resistance.…”

“…9,[12][13][14][15][16][17][18][19][20][21][22]25 This problem can be solved by modifying the route of LnCoO 3 production to directly vary micromorphological features, which are crucial concerning the catalytic activity. 27 Similarly to other complex oxides, LnCoO 3 are most commonly prepared via swift and simple sol-gel techniques 14,16,23,25,[28][29][30][31][32][33][34][35][36] based on the thermolysis of the in situ prepared gelous Ln-Co complexes with anions of citric acid and glycine; other polyfunctional carboxylic acids are rarely involved. However, the insolubility of such complexes hinders the direct modification of their composition and morphology.…”

Elucidating the role of earth alkaline doping in perovskite-based methane dry reforming catalysts

“…31 In order to search for alternative DRM materials, Smcontaining catalysts have evolved as potentially promising. This is essentially referred to the fact that Sm 2 O 3 , like La 2 O 3 , is reported to be capable of forming a samarium oxycarbonate species [34][35][36] and that the Ni/Sm 2 O 3 interface showed superior ability in the DRM process. 37 A particular important sub-class of Sm-based perovskite catalysts are the associated cobalt-containing materials.…”

Dry Reforming of Propane over γ-Al2O3 and Nickel Foam Supported Novel SrNiO3 Perovskite Catalyst

“…A-site replacement with alkaline earth metal is expected to enhance the carbon susceptible and thermal stability, and the B-site alteration is expected to increase the activity of the catalyst [18,19]. In last decade, many researchers have been widely reported LaNiO 3 [20][21][22], LaFeO 3 [23], SmCoO 3 [24] and also partial substitution of B-site perovskite catalysts show the higher activity, stability, and resistance to coke formation even at elevated temperature. The perovskite catalysts increase the syngas production in dry reforming reaction [25][26][27].…”
