摘要：

A series of supported Fe/Co catalysts with Y zeolite-containing K, Ce or La used as support were synthesized to perform CO2 hydrogenation to linear-alpha olefins (LAOs). Medium acid-base properties and the content of active carbide (Fe5C2) are both affected by the different ion-exchange strategies and heteroatom doping used, which are crucial for the CO2 conversion to LAOs process. CO2 conversion (25.9%) and highest C-4+(=) alkenes (45.9%), of which the formation of LAOs accounts for 78.9%, were achieved after the supported bimetallic Fe/Co-Y catalyst containing K+-exchange zeolite was used.
