摘要：
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-C3N4 (2D O-g-C3N4) has been prepared and used as photocatalyst for degradation of environmental pollutants. The as-prepared 2D O-g-C3N4 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. (C) 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
