“…As shown in figure 1(c), PAF-45 and 1 wt% CQDs/PAF-45 have similar absorption bands, indicating that the C-C coupling skeleton resulting from the scholl-based reaction between the initial monomeric benzene rings is not specifically changed by the doping of CQDs. Furthermore, through referencing the relevant reference on CQDs, we found that most CQDs exhibit stretching vibration peaks of O-H, C=O, and C-O around 3800-3300, 1686, and 1066 cm −1 , respectively [32]. Upon observing the infrared spectrum of the CQDs in figure 1(c), it is evident that the CQDs we synthesized exhibit significant absorption peaks around 3500 cm, 1700 cm, and 1100 cm −1 .…”

Modification and functionalization of porous aromatic framework (PAF) materials have emerged as crucial research directions in various fields. In this study, we employed a hydrothermal method to synthesize a carbon quantum dots (CQDs) solution. By loading different amounts of CQDs onto the surface of PAF-45 material through ultrasonic and hydrothermal treatments, we successfully formed CQDs/PAF-45 composite materials. The introduction of CQDs effectively transformed the hydrophobic nature of PAF-45 into a hydrophilic material, thereby overcoming the challenge of achieving efficient contact between PAF catalysts and reactants in aqueous solutions. In the photocatalytic degradation experiments of Rhodamine B (RhB), tetracycline, CQDs/PAF-45 composite materials surpassed that of the pristine PAF-45 material. Notably, the 1 wt% CQDs/PAF-45 composite material exhibited the highest photocatalytic activity, with degradation efficiencies for Rhodamine B, tetracycline, and phenol approximately 1.4 times, 1.5 times and 1.5 times higher than those of the PAF-45 material, respectively.
