Stabilizing a Vanadium Oxide Catalyst by Supporting on a Metal–Organic Framework

Abstract

Abstract NU‐1000 is a robust and highly porous Zr‐based metal–organic framework (Zr‐MOFs) that has been proven to be an excellent catalyst support because of its well‐defined crystal structure, protonic grafting sites on its nodes, and thermal stability, all of which advantageously offer the possibility to study the nature of the catalytic reactive sites. Herein, we present a vanadium‐oxide catalyst supported on NU‐1000 synthesized by solvothermal deposition in MOFs (SIM), namely, V‐NU‐1000. The catalytic activity of V‐NU‐1000 was investigated by studying the oxidation of 4‐methoxybenzyl alcohol under an O 2 atmosphere; this catalyst showed higher conversion and higher selectivity than vanadium‐oxide supported on high‐surface‐area zirconia (V‐ZrO 2 ). The stability of V‐NU‐1000 was confirmed by recyclability and leaching tests, in which recycled V‐NU‐1000 had catalytic ability comparable to that of the fresh catalyst, and no loss in the metal loading was found in recollected V‐NU‐1000.
