Fe2O3 Hollow Microspheres as Highly Selective Catalysts to α-olefins

Abstract

We rationally designed and facile synthesized an excellent Fischer-Tropsch synthesis (FTS) catalyst based on mesoporous Fe2O3 microspheres derived from Fe–glycerate via an annealing treatment in air. The synthesis of Fe-containing precursor is the key step in the fabrication process of Fe2O3 microspheres with different interior structure (solid spheres, yolk-shell spheres and hollow spheres). The as-prepared catalysts have been characterized systematically to elucidate their structure-dependent catalytic property. The fine control of Fe2O3 with different interior structure and tunable pore size optimized distinctly the FTS activity and shifted the product distribution towards heavy hydrocarbons (especially, α-olefin) compared with the traditional iron catalysts. In light of the characterization results, the excellent FTS performance of Fe2O3 hollow spheres can be attributed to the hollow and mesoporous structures.
