Hydroxylation of benzene to phenol over heteropoly acid H₅PMo₁₀V₂O₄₀ supported on amine-functionalized MCM-41.

ABSTRACT: Supported catalysts with Keggin type heteropoly acids (H₅PMo₁₀V₂O₄₀) loaded onto amine-functionalized MCM-41 for the catalytic hydroxylation of benzene to phenol with H₂O₂ were prepared by a wet impregnation method. The effects of the preparation conditions on the properties and activity of the supported catalysts were fully investigated. The results showed that the catalyst retained the mesoporous structure of MCM-41 and H₅PMo₁₀V₂O₄₀ was dispersed uniformly on the surface of the amine-functionalized MCM-41. Meanwhile, the reusability and catalytic performance of the catalyst were affected by two key factors, i.e., the interaction between the heteropoly acid and the surface
