Polyoxometalate-based 3DOM ZrO2 material for deep oxidative desulfurization of DBT with ultrahigh stability
Source abstract
Abstract
Highly ordered three-dimensional (3DOM) macroporous polyoxometalate (POM)-based zirconia hybrids with relatively high surface area and interconnected pore structure have been fabricated by colloidal crystal template method. Owing to the evenly distributed POM active sites, large-scaled 3D ordered macroporous structure, and high porosity of as-synthesized POM-based ZrO2 composite, it exhibits excellent extractive-oxidative desulfurization activity and recyclability. 500 ppm of dibenzothiophene (DBT) in the model fuel can be removed within 2 h under mild conditions and no obvious loss of catalytic activity even after 20 times. The oxidative reaction of DBT follows pseudo-first-order kinetics, corresponded to an Arrhenius activation energy of 61.1 kJ/mol.
