Title: Adsorption of a catalytically accessible polyoxometalate in a mesoporous channel-type metal–organic framework

A Keggin-type polyoxometalate (H 3PW 12O 40) was incorporated into a mesoporous Zr-based MOF (NU-1000) via an impregnation method in aqueous media, resulting in the hybrid material, PW 12@NU-1000. The POM@MOF composite was characterized by a suite of physical methods, indicating the retention of crystallinity and high porosity of the parent MOF. The hybrid material was also stable to leaching in aqueous media at varying pH. Lastly, the material was tested as a heterogeneous catalyst for the oxidation of 2-chloroethyl ethyl sulfide using hydrogen peroxide as the oxidant. PW 12@NU-1000 was shown to have a higher catalytic activity than either of the individual constituents alone.
