Catalytic Oxidation of Chlorobenzene over Amorphous Manganese-Chromium Catalysts Supported by UiO-66-Derived ZrOx.

The development of efficient catalysts with longevity to remove chlorobenzene is challenging due to Cl poisoning. Herein, a series of Mn-Cr/ZrO catalysts supported by Zr-based metal-organic framework (UiO-66)-derived ZrO was prepared and investigated for chlorobenzene (CB) catalytic oxidation. MnCr/ZrO-M prepared via a wet impregnation method presented an amorphous structure, indicating the homogeneous dispersion of Cr and Mn, which improved acid and redox properties.
