摘要
作为一种非金属材料,石墨相氮化碳(g-C_(3)N_(4))具有成本低、稳定性好、可修饰性强等优点,在光催化领域备受关注。与体相g-C_(3)N_(4)不同,零维结构的石墨相氮化碳量子点(CNQDs)不仅保留了g-C_(3)N_(4)的优点,还具有独特的量子限域效应和特殊的光电效应及良好的生物相容性,在化学检测、光电器材及生物医药等方面表现突出。系统介绍了CNQDs的主要制备方法,包括超声法、水热法、微波辅助溶剂热法、固相法、准化学气相沉积法等;基于CNQDs独特的荧光特性,重点介绍了CNQDs在Fe^(3+)/Fe^(2+)、Hg^(2+)等金属离子,Cl^(-),F^(-),I^(-),NO_(2)^(-)等阴离子,酚类、三聚氰胺等有机化合物及胆固醇、抗坏血酸、谷胱甘肽、核黄素等各类生物医药试剂的检测;最后,分析了CNQDs在检测领域目前面临的主要问题,并对将来的发展趋势进行了展望。
As a non-metallic material,graphite carbon nitride(g-C_(3)N_(4))has attracted much attention in the field of photocatalysis due to its low cost,good stability and strong modifiability.Unlike bulk g-C_(3)N_(4),graphite carbon nitride quantum dots(CNQDs)with zero dimensional structure not only retain the advantages of g-C_(3)N_(4),but also have unique quantum confinement effect,special photoelectric effect and good biocompatibility,which are outstanding in chemical detection,photoelectric equipment and biomedicine.The main preparation methods of CNQDs were systematically introduced in this review,including ultrasonic method,hydrothermal method,microwave-assisted solvothermal method,solid-phase method,quasi-chemical vapor deposition method,etc.Based on the unique fluorescence characteristics of CNQDs,the detection of CNQDs in metal ions such as Fe^(3+)/Fe^(2+),Hg^(2+),anions such as Cl^(-),F^(-),I^(-),NO_(2)^(-),organic compounds such as phenols and melamine,and various biopharmaceutical reagents such as cholesterol,ascorbic acid,glutathione,riboflavin,etc.were emphatically introduced.Finally,the main problems faced by CNQDs in the detection field were analyzed,and the future development trend was prospected.
