摘　　要：为提高服装面料在太阳光下的光催化自清洁性能,采用柠檬酸和尿素制备氮碳量子点(N-CQDs),并通过水热法与纳米二氧化钛(TiO_(2))共同整理粘胶织物,制备出太阳光响应复合光催化纺织品。借助扫描电子显微镜、红外光谱仪、紫外-可见分光光度计等对整理前后的粘胶织物进行表征,测试其光学吸收性、光催化降解脱色性和稳定性,研究N-CQDs、TiO_(2)及其复合体系降解罗丹明B的协同构效机制。结果表明:在模拟日光下催化降解罗丹明B 5 h时,经N-CQDs/TiO_(2)整理的粘胶织物脱色率为76.5%,比经TiO_(2)整理粘胶织物的脱色率(51.3%)提高了49.1%,且循环降解6次后,脱色率仍能达到62.34%。In order to improve the self-cleaning performance of clothing fabrics under sunlight,nitrogen-doped carbon quantum dots(N-CQDs)were prepared from citric acid and urea,and the composite photocatalytic textiles were created through hydrothermal treatment of viscose fabrics loaded with nitrogen-doped carbon quantum dots and nano titanium dioxide.The viscose fabrics were characterized by means of scanning electron microscope,infrared spectrometer,and ultraviolet-visible photometer,and heir optical absorption,photocatalytic degradation and stability were tested.The synergistic mechanism of degradation of Rhodamine B(RhB)by N-CQDs,TiO_(2) and their composite systems were studied.The results show that the decolorization rate of fabric loaded with N-CQDs/TiO_(2) is 76.5%,which is 49.1%higher than that of fabric loaded with TiO_(2),and the decolorization rate can still reach 62.34%after 6 cycles of photocatalytic degradation of RhB.
