文摘

A novel CeO2@HZSM-5hybridcompositeswithsandwichandcore-shellstructurewasdesignedandprepared. (*). CeO2 nanosheets were completely encapsulated by continuous and dense HZSM-5 membranes. CeO2@HZSM-5 exhibited a better resistance to the coking and chlorine poisoning for DCE oxidation. The formation of polychlorinated hydrocarbons (PCHs) by-products over CeO2@HZSM-5 was significantly inhibited.
