Fabrication of PW11Zn@MOF-808 and its catalytic activity for oxidative desulfurization of fuel oil: Kinetics, thermodynamics and mechanism

At present, metal-organic frameworks (MOFs) supported with Keggin-type polyoxometalates (POMs) have been proven to be an effective approach for the development of high-performing heterogeneous catalysts. Herein, a Keggin-type PW11Zn was encapsulated within MOF-808 (PW11Zn@MOF-808) through an environ...
