Direct conversion of CO₂ to hydrocarbons using Earth-abundant metal catalysts offers a promising solution for mitigation of rapidly increasing CO₂ emissions. Non-noble metals, such as Fe, present costeffective alternatives to noble metals but face stability challenges. The incorporation of small amount of ruthenium1 and Supported Ionic Liquids (SILs) enhances catalytic stability and selectivity toward higher hydrocarbons by improving particle size control and metal-metal interactions. This study shows highly enhanced catalytic activity in CO2 conversion using Fe-Ru synergistic interactions on the surface of SILmodified supports, as well as very promising catalyst longevity as observed from stable time-on-stream performance for >150 hours.

Abstract
Direct conversion of CO₂ to hydrocarbons using Earth-abundant metal catalysts offers a promising solution for mitigation of rapidly increasing CO₂ emissions. Non-noble metals, such as Fe, present costeffective alternatives to noble metals but face stability challenges. The incorporation of small amount of ruthenium1 and Supported Ionic Liquids (SILs) enhances catalytic stability and selectivity toward higher hydrocarbons by improving particle size control and metal-metal interactions. This study shows highly enhanced catalytic activity in CO2 conversion using Fe-Ru synergistic interactions on the surface of SILmodified supports, as well as very promising catalyst longevity as observed from stable time-on-stream performance for >150 hours.| File | Dimensione | Formato | |
