Abstract:
A kind of core–shell catalyst with Fe–Zn–Zr as the core and a zeolite (HZSM-5, Hbeta, and HY) as the shell was synthesized by a simple cladding method. The catalyst has an obvious confinement effect on the synthesis of isoalkanes by CO₂ hydrogenation. Especially, the Fe–Zn–Zr@HZSM-5–Hbeta catalyst with a double-zeolite shell exhibits an extraordinary high i-HC/t-HC ratio.
