Although ultrathin two‐dimensional (2D) nanomaterials have aroused great attention, the preparation methods are still difficult to meet the requirements. Herein, two‐dimensional oxygen‐modified single layer g‐C 3 N 4 (2D O‐g‐C 3 N 4 ) has been prepared and used as photocatalyst for degradation of environmental pollutants. The as‐prepared 2D O‐g‐C 3 N 4 exhibited excellent photocatalytic activity for degradation of the organic dyes and 4‐chlorophenol (4‐CP). Through the DMPO spin‐trapped ESR spectroscopy analysis, the photocatalytic mechanism was researched in detail.
