Abstract

Despite extensive research efforts in CO2 hydrogenation, achieving a high yield of liquid fuels remains a significant challenge due to the limited conversion of CO2 and the considerable formation of undesired C1 byproducts. In this study, we report a record-high yield of liquid fuels from CO2 hydrogenation facilitated by an Fe-Zn catalyst enriched with interfacial sites. These interfacial sites effectively enhanced carbon chain growth through the synergistic interaction of the carbide pathway and CO insertion while simultaneously suppressing the formation of CO and CH4. Consequently, the selectivity for undesired C1 byproducts was minimized to 14.7%, while maintaining a high selectivity of 72.2% for liquid fuels. Under optimized reaction conditions including 360 °C, 4.0 MPa, 4,000 mL gcat-1 h-1, and CO2/H2 = 3, the liquid fuel yield reached 31.7% at a single-pass CO2 conversion of 48.2%.
