For this purpose, LSC was synthesized by the citrate sol–gel method and characterized by complementary analytical techniques. The catalytic activity was studied for the as-prepared and prereduced LSC and compared with the undoped LaCoO3−δ (LCO) at several feed gas compositions. Furthermore, the degradation and regeneration of LSC under repeated redox cycles were studied. The results evidenced that the increase in the water/methanol ratio under SRM, and the O2 addition under OSRM, increased the CO2 formation and decreased both the H2 selectivity and catalyst deactivation caused by carbon deposition. Methanol conversion of the prereduced LSC was significantly enhanced at a lower temperature than that of as-prepared LSC and undoped LCO. This was attributed to the performance of metallic cobalt nanoparticles highly dispersed under reducing atmospheres. The reoxidation program in repetitive redox cycles played a crucial role in the regeneration of catalysts, which could be regenerated to the initial perovskite structure under a specific thermal treatment, minimizing the degradation of the catalytic activity and surface. 000126946 536__ $$9info:eu-repo/grantAgreement/ES/AEI/PID2019-107106RB-C32 000126946 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000126946 590__ $$a5.5$$b2023 000126946 592__ $$a1.467$$b2023 000126946 591__ $$aCHEMISTRY, PHYSICAL$$b55 / 178 = 0.309$$c2023$$dQ2$$eT1 000126946 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b116 / 439 = 0.264$$c2023$$dQ2$$eT1 000126946 591__ $$aENERGY & FUELS$$b64 / 171 = 0.374$$c2023$$dQ2$$eT2 000126946 593__ $$aElectrical and Electronic Engineering$$c2023$$dQ1 000126946 593__ $$aElectrochemistry$$c2023$$dQ1 000126946 593__ $$aMaterials Chemistry$$c2023$$dQ1 000126946 593__ $$aChemical Engineering (miscellaneous)$$c2023$$dQ1 000126946 593__ $$aEnergy Engineering and Power Technology$$c2023$$dQ1 000126946 594__ $$a10.3$$b2023 000126946 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126946 700__ $$0(orcid)0000-0002-7819-8956$$aLaguna-Bercero, M.
