AB  - Ru species were loaded on a two-dimensional (2D) material of graphitic carbon 
      nitride (2D g-C(3)N(4)) to serve as the efficient AOP catalysts. The catalytic 
      activity was closely related to the dispersion degree of Ru, as determined by the 
      inherent nanoarchitecture of the supporting material. Ultrathin g-C(3)N(4) 
      nanosheets with a unique porous structure were fabricated by further thermally 
      oxidizing and etching bulk g-C(3)N(4) (bCN) in air. Homogeneous dispersion of Ru 
      species was successfully achieved on the porous few-layered g-C(3)N(4) nanosheets 
      (pCN) by stirring, washing, freeze drying and annealing processes to obtain 
      Ru-pCN catalysts, whereas bCN or multilayered g-C(3)N(4) (mCN) led to the 
      aggregation of Ru nanoparticles in Ru-bCN and Ru-mCN materials. The conventional 
      impregnation method also caused the resulting Ru-pCN-imp catalyst with 
      undesirable Ru aggregation in spite of employing pCN. The optimal 4.4Ru-pCN 
      removed 100% of 2,4,6-trichlorophenol (TCP) within only 3 min, superior to its 
      counterpart samples, and exhibited remarkable degradation efficiencies for methyl 
      orange, neutral red, 4-chlorophenol, tetracycline and oxytetracycline. 
      Mechanistic studies suggested that four radicals, e.g., (*)OH, SO(4)(* -), O(2)(* 
      -) and (1)O(2) were generated during the peroxymonosulfate (PMS) activation, in 
      which SO(4)(* -) and (1)O(2) played a major role.
