Metal–support interactions in Fe–Cu–K admixed with SAPO-34 catalysts for highly selective transformation of CO2 and H2 into lower olefins

Abstract

Strong interactions between Fe–Cu–K and SAPO-34 in admixed catalysts composed of Fe–Cu–K and SAPO-34 result in the changes of structures, reducible properties and mass transfer between Fe-Cu-K and SAPO-34, which contribute to good activities.
