Identifying highly efficient catalysts for direct CO₂ hydrogenation to liquid hydrocarbons is crucial for CO₂ utilization via chemical conversion using renewable resources, the so-called Power-to-Liquids. In this study, well-defined mesoporous carbon (MPC) of 6.9 nm pore size was synthesized as a support material for Fe oxycarbide nanoparticles, which serve as active sites for the CO₂ hydrogenation reaction, combining reverse water-gas shift and Fischer-Tropsch reactions. The unique physicochemical properties of MPC favored the formation of an active carbidic Fe phase and the rapid diffusion of produced hydrocarbons which resulted in an enhanced CO₂ conversion and long-chain hydrocarbon selectivity. As a result, the MPC supported Fe catalyst showed C₅₊ hydrocarbon selectivity of 44.5% with a CO₂ conversion rate of 50.6% (300 °C, 2.5 MPa, H₂/CO₂ = 3).

对于将CO ₂直接加氢成液态烃的高效催化剂，对于通过使用可再生资源（即所谓的“液体转化为液体”）进行化学转化来利用CO ₂至关重要。在这项研究中，合成了孔径为6.9 nm的定义明确的介孔碳（MPC）作为碳氧化铁纳米颗粒的支撑材料，该碳纳米管用作反向CO- ₂氢化反应的活性位点，并结合了反向水煤气变换和Fischer-Tropsch反应。MPC独特的理化性质有利于形成活性的碳化铁相，并且所产生的碳氢化合物迅速扩散，从而提高了CO _2的含量。转化率和长链烃的选择性。结果，MPC负载的Fe催化剂显示出C ₄₊烃选择性为44.5％，CO ₂转化率为50.6％（300℃，2.5MPa，H ₂ / CO ₂  ＝ 3）。
