Ligand Modified Metal Organic Framework UiO-66: A Highly Efficient and Stable Catalyst for Oxidative Desulfurization

It is reported that the UiO-66(Zr) material could catalyze oxidative desulfurization (ODS) reaction, but its stability is inferior. In this work, a family of functionalized UiO-66(Zr) with different groups (–NH2, –NO2, –Br) were prepared to enhance this material’s activity and stability. Characterizations and ODS tests show that the groups have profound influence over the physicochemical properties of UiO-66(Zr). Among functionalized UiO-66(Zr), UiO-66(Zr)-NO2 exhibited the best ODS activity, their ODS performance is linear correction with their Hammett values. Recycling experiments indicate UiO-66(Zr)-NO2 has no deactivation.
