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 (–NH 2 , –NO 2 , –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)-NO 2 exhibited the best ODS activity, their ODS performance is linear correction with their Hammett values. Recycling experiments indicate UiO-66(Zr)-NO 2 has no deactivation.
