How does the pore structure of β-zeolite influence the catalytic performance of Na2WO4 in the oxidative coupling of methyl chloride to vinyl chloride?

Label:chem

Topic
The pore structure of a support material can significantly affect the dispersion and activity of catalytic species.
Answer
The pore structure of β-zeolite, characterized by its regular shape and suitable size distribution, provides an accurate geometric matching effect for Na2WO4. This ensures that Na2WO4 is homogeneously distributed within the β-zeolite matrix, leading to superior catalytic performance with high CH3Cl conversion (81.5%), C2H3Cl selectivity (42.4%), and C2H3Cl yield (34.6%).
