AB  - In present work, we studied a novel Fe/C nanomaterial fabricated using Fe-based 
      metal organic frameworks (MOFs) as precursors through thermal pyrolysis to 
      catalyze gamma irradiation-induced degradation of antibiotics, cephalosporin C 
      (CEP-C) and sulfamethazine (SMT) in aqueous solution. The MOFs-derived Fe/C 
      nanomaterials (DMOFs) had the regular octahedrons structure of MOFs and contained 
      element C, Fe and O, while Fe degrees  with a fraction of Fe(3)O(4) and Fe(2)O(3) were 
      identified. Results showed that DMOFs addition could accelerate the generation of 
      OH during gamma irradiation, while the intermediates of bonds cleavages of 
      antibiotic molecules and OH addition were identified. DMOFs were more effective 
      to improve the decomposition of antibiotic having the higher adsorption capacity 
      like SMT. The degradation rate of CEP-C and SMT increased by 1.3 times and 1.8 
      times, and TOC reduction at 1.0 kGy reached 42 % and 51 %, respectively by 
      gamma/DMOFs treatment, while only 20.2 % (CEP-C) and 4.5 % (SMT) of TOC reduction 
      were obtained by gamma-irradiation alone. The crystal structure, functional groups 
      and magnetism of DMOFs changed slightly after gamma irradiation, which made it 
      possible to be reused. DMOFs were promising to enhance the degradation of 
      antibiotics during gamma irradiation.
