摘要
Carbon dots/graphite carbon nitride(CDs/g-C_(3)N_(4)),a novel composite photocatalyst,has shown great po-tential for applications in energy regeneration and environmental remediation owing to its following advantages:metal-free,low cost,easily tunable,and excellent photocatalytic performance.Hence,we reviewed the development of synthetic strategies,photocatalytic enhancement mechanisms,and pho-tocatalytic applications of CDs/g-C_(3)N_(4) in this study.First,the three composite strategies of CDs and g-C_(3)N_(4)-self-assembly,solvothermal,and calcination polymerization are outlined,and their advantages and disadvantages are described in detail.Moreover,the photocatalytic enhancement mechanism of the com-posite strategies was elucidated according to the variation trends of CDs/g-C_(3)N_(4) band structure,electronic properties,light absorption range,and interfacial charge transfer.Then,the applications of CDs/g-C_(3)N_(4) in hydrogen evolution,pollutant degradation,CO_(2) reduction,and bacterial disinfection in recent years are reviewed systematically.Finally,the current obstacles and future research directions of CDs/g-C_(3)N_(4) are discussed from the perspective of preparation technology and practical applications,respectively.
