Nanoporous Carbon Catalysts in Fischer–Tropsch SynthesisKiara Montiel CentenoOrdered mesoporous carbons have emerged as versatile supports for Fischer–Tropsch catalysts due to their high surface area, tunable pore architectures, and chemical stability. However, the influence of active-metal identity on product selectivity within a common carbon framework remains insufficiently understood, particularly when Fe and Co are compared under rigorously identical conditions. To address this aspect, we prepared Fe- and Co-based catalysts with comparable nominal metal loadings supported on CMK-5 carbon material and evaluated their structural, surface, and catalytic properties. Comprehensive characterization revealed distinct metal-dependent behaviors, and catalytic testing between 423 and 598 K at 2 MPa showed that the catalyst CMK-5(Co10) exhibited substantially higher activity, whereas CMK-5(Fe10) provided a more stable product distribution and exclusively paraffinic C2–C3 products across the studied temperature range. In contrast, CMK-5(Co10) displayed a pronounced temperature-dependent selectivity, with increasing methane formation and the emergence of olefinic C2–C3 species at intermediate and high temperatures. Chain-growth probabilities were consistent with these trends. Complementary Density Functional Theory and Kinetic Monte Carlo analyses indicated stronger binding of carbonaceous intermediates on Fe clusters and more accessible C–C coupling pathways on Co clusters. Together, these results clarify how active-metal identity governs selectivity within a shared CMK-5 architecture and provide guidelines for designing carbon-supported Fischer–Tropsch catalysts with controlled product distributions.

Electrolysis training for teachers at IES Javier García Tellez, as part of a partnership with the Prometeo ProjectMELISA JULIETA GOMEZDr. Melisa J. Gomez, along with Dr. Liliana Analía Diaz and Dr. Rosa María Ladera Gallardo, collaborated on the Prometeo project to provide training in hydrogen production technologies. Prometeo aims to introduce key elements of electrochemical energy production, chemical storage, to address potential process challenges. On April 29, 2026, a meeting was held featuring demonstrations of experimental activities related to electrolysis and fuel cells, aimed at training teachers from IES Javier García Téllez and, through them, their students. All three researchers are part of the CIIAE - Iberian Centre for Research in Energy Storage (#CIIAE). Dr. Melisa J. Gomez is a fellow of the #Talent4Iberia programme, co-funded by the European Union's Horizon Europe research and innovation programme under the Marie Skłodowska-Curie Actions (#MSCA) and the Junta de Extremadura. It was a highly engaging and rewarding experience, fostering meaningful exchange, strengthening connections between academia and education, and contributing to the dissemination of knowledge in sustainable energy technologies. Initiatives like this play a key role in inspiring future professionals and advancing collaborative learning. url: https://www.linkedin.com/posts/melisa-julieta-g%C3%B3mez-10137826_ciiae-talent4iberia-msca-ugcPost-7456988543031132161-wBCa?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAO8o_oB6rqYv5OsY9EaXziYr9pUxSUeLCk
