What is the role of β-zeolite in the dispersion of Na2WO4 nanoclusters for the oxidative coupling of methyl chloride to vinyl chloride?

Label:chem

Topic
The dispersion of active species like Na2WO4 on a catalyst support is crucial for achieving high catalytic activity and selectivity. β-zeolite is used as a support material in this study.
Answer
β-zeolite provides an optimal pore structure with suitable pore sizes, high specific surface area, and substantial cavity volume, which allows Na2WO4 molecules to enter and remain stably confined within its internal channels. This results in high dispersion of Na2WO4 nanoclusters, preventing aggregation and enhancing catalytic performance.
