AB  - The poor conductivity, poor stability, and agglomeration of iron-based metal 
      organic framework MIL-88A(Fe) limit its application as persulfate (PS) activator 
      in water purification. Herein, MXene-supported MIL-88A(Fe) composites (M88A/MX) 
      were synthesized to enhance its adsorption and catalytic capability for 
      tetracycline (TC) removal. Scanning electron microscope (SEM), X-ray 
      diffractometer (XRD), Fourier transform infrared spectrometer (FT-IR), and X-ray 
      photoelectron spectroscopy (XPS) were used to characterize prepared materials, 
      confirming the successful attachment of MIL-88A(Fe) to the surface of MXene. 
      M88A/MX-0.2 composites, prepared with 0.2 g MXene addition, exhibit optimal 
      degradation efficiency, reaching 98% under conditions of 0.2 g/L M88A/MX-0.2, 
      1.0 mM PS, 20 ppm TC, and pH 5. The degradation rate constants of M88A/MX-0.2 
      were 0.03217 min(-1), which was much higher than that of MIL-88A(Fe) 
      (0.00159 min(-1)) and MXene (0.00626 min(-1)). The removal effects of reaction 
      parameters, such as dosage of M88A/MX-0.2 and PS; initial solution pH; and the 
      presence of the common co-existing constituents (humic acid and the inorganic 
      anions) were investigated in detail. Additionally, the reuse of M88A/MX-0.2 
      showed that the composites had good cycling stability by recurrent experiments. 
      The results of electron paramagnetic resonance (EPR) and quenching experiments 
      indicated that .OH, .SO(4)(-), and .O(2)(-) were involved in the M88A/MX-0.2/PS 
      system where persulfate oxidation process was activated with prepared 
      M88A/MX-0.2. In addition, the intermediates of photocatalytic degradation were 
      determined by HPLC-MS, and the possible degradation pathways of the target 
      molecules were inferred. This study offered a new avenue for sulfate-based 
      degradation of Fe-based metal organic framework.
