Core Insights - The research team from the Shanxi Coal Chemical Research Institute and Peking University has achieved a breakthrough in iron-based Fischer-Tropsch synthesis catalysts, achieving less than 1% carbon dioxide selectivity and over 85% olefin selectivity, providing new approaches for clean utilization of high-carbon resources [1][2]. Group 1: Research Achievements - The study published in "Science" demonstrates a significant advancement in catalyst performance, crucial for the production of olefins, which are key raw materials for synthetic fibers, rubber, and plastics [1]. - The traditional iron-based catalysts have limitations due to their multiple activities, leading to high carbon dioxide generation, which restricts carbon utilization efficiency and olefin selectivity [1]. Group 2: Innovative Strategies - The research team introduced a trace halogenated alkane co-feeding strategy, which allows for effective regulation of surface oxygen species at the molecular level, enhancing catalytic performance without altering the catalyst formulation [2]. - The strategy enables near-zero carbon dioxide emissions and high olefin selectivity, showcasing a "plug-and-play" advantage for broader applications [2]. Group 3: Future Directions - The team plans to further explore the industrial scaling and long-term stability of the halogen regulation strategy, aiming to promote its application in coal-to-liquid, natural gas conversion, and biomass utilization [2].
