Syngas-to-olefins over MOF-derived ZnZrOx and SAPO-34 bifunctional catalysts

ZnZrOx nanoparticles were prepared by MOF calcination and co-precipitation methods and used as metal oxide components of bifunctional catalysts for syngas-to-olefins (STO). The results of characterization analysis, like XRD, XPS, H2-TPR and CO-TPD, illustrated that different preparation methods appa...
