碳点作为单一光催化剂的最新进展OA

Carbon dots(CDs),as a class of highly promising multifunctional carbon nanomaterials,have emerged as a hot research topic in photocatalysis due to their strong visible-light absorption,favorable optical properties,and tunable bandgap structures.In recent years,extensive efforts have been devoted to enhancing the catalytic performance by combining CDs with other catalysts to form complexes.Beyond that,CDs also present a decent catalytic performance in various fields.However,summaries focusing on photocatalytic performance and mechanisms of CDs as a single-component photocatalyst remain scarce.A thorough understanding of structural characteristics and modulation strategies of the CDs is crucial for further advancing their photocatalytic applications.This review systematically summarizes the intrinsic structural features of CDs,performance enhancement strategies,including elemental doping and surface functionalization,and their applications as single-component catalysts in diverse photocatalytic reactions.
