Oxidative desulfurization is considered to be one of the most promising methods for producing ultra‐low‐sulfur fuels because it can effectively remove refractory sulfur‐containing aromatic compounds under mild conditions. In this work, the oxidative desulfurization performance over UiO‐66(Zr) is greatly enhanced by Ti ion exchange. This strategy is not only efficient for UiO‐66(Zr) with crystal defects but also for UiO‐66(Zr) with high crystallinity. In particular, the performance of UiO‐66(Zr) with high crystallinity in the oxidative desulfurization of dibenzothiophene can be improved more than 11‐fold, which can be mainly attributed to the introduction of active Ti sites.
