Abstract

Converting CO₂ to liquid (C₅₊) hydrocarbons remains a significant hurdle. Our study shows that CoFe/HZSM-5 boosts C₅₊ selectivity to 73.4%, up from 59% for Fe/HZSM-5. This study highlights the pivotal roles of zeolite acidity and catalyst proximity in this improvement. These insights pave the way for more effective CO₂ utilization.
