费托合成 (FTS) 是一种通用技术，可利用源自煤炭、天然气、页岩气、生物质、固体废物甚至 CO ₂等非石油碳资源的合成气生产高质量燃料和关键组成化学品。然而，FTS的产物选择性始终受限于Anderson-Schulz-Flory (ASF)分布，以及选择性控制、节能、CO _{2等关键科学问题。}减排仍然挑战当前的FTS技术。在此，我们回顾了 FTS 领域最近取得的重大进展，以高选择性地获得特定的目标产品，包括燃料、烯烃、芳烃和高级醇。这些成就是通过开发高效催化剂和基于集成过程的受控反应途径来实现的。阐明了催化活性位点的结构性质和已建立的结构-性能关系。此外，我们特别关注碳利用效率，总结了调整增值化学品优先形成的努力和降低CO ₂选择性的策略。还讨论了未来具有高碳效率的 FTS 技术发展的挑战和前景。

Advances in Selectivity Control for Fischer–Tropsch Synthesis to Fuels and Chemicals with High Carbon Efficiency

Fischer–Tropsch synthesis (FTS) is a versatile technology to produce high-quality fuels and key building-block chemicals from syngas derived from nonpetroleum carbon resources such as coal, natural gas, shale gas, biomass, solid waste, and even CO₂. However, the product selectivity of FTS is always limited by the Anderson–Schulz–Flory (ASF) distribution, and the key scientific problems including selectivity control, energy saving, and CO₂ emission reduction still challenge the current FTS technology. Herein, we review recent significant progress in the field of FTS to obtain specific target products including fuels, olefins, aromatics, and higher alcohols with high selectivity. These achievements are enabled by developing highly efficient catalysts and a controlled reaction pathway based on an integrated process. The structural nature of catalytic active sites and established structure–performance relationships are clarified. Moreover, we specially focus on the carbon utilization efficiency, and the efforts to tune the preferential formation of value-added chemicals and strategies to reduce CO₂ selectivity are summarized. The challenges and the perspectives for future FTS technology development with high carbon efficiency are also discussed.
