To form stable the graphitic carbon nitride (g-C₃N₄) composite photocatalyst with high repeatability, the hydrogen bonding composite was facilely built by g-C₃N₄ with two perylene anhydride derivatives (3,4,9,10-perylenetetracarboxylic acid anhydride (PTCDA) and 1,6,7,12-tetrachloroperylene-3,4,9,10- tetracarboxylic acid (TClPTCDA)). Intermolecular hydrogen bond was confirmed by analysis of FT-IR, XPS and DSC data. In contrast with their raw materials, the composite photocatalysts would significantly improve the photocatalytic activity to rhodamine B under visible light radiation. Furthermore, the TClPTCDA/g-C₃N₄ (TClP-g) prossesses higher photocatalytic activity than that of PTCDA/g-C₃N₄ (P-g) under same experimental condition.

为了形成稳定的，具有高重复性的石墨氮化碳（gC ₃ N ₄）复合光催化剂，通过gC ₃ N ₄与两种per酸酐衍生物（3,4,9,10-tetra四羧酸酐（PTCDA） ）和1,6,7,12-四氯per-3,4,9,10-四羧酸（TC1PTCDA））。通过FT-IR，XPS和DSC数据的分析证实了分子间氢键。与它们的原料相比，复合光催化剂将在可见光辐射下显着提高对若丹明B的光催化活性。此外，TClPTCDA / gC ₃ N ₄在相同的实验条件下（TClP-g）具有比PTCDA / gC ₃ N ₄（Pg）更高的光催化活性。
