Mixed‐Valence Ce/Zr Metal‐Organic Frameworks: Controlling the Oxidation State of Cerium in One‐Pot Synthesis Approach

The preparation of MOFs including a metal with an easily exchangeable oxidation state, while maintaining the same crystal structure and stability, is paramount importance for myriad applications. In this work, new synthesis method reported that can be used to prepare Ce/Zr-MOFs (UiO-66 structure) having only Ce(III), mixed-valence Ce(IV)/Ce(III), or Ce(IV) cations, as desired. materials are characterized using large number techniques, X-ray absorption photoelectron spectroscopies.
