摘要:

碳点(CDs)作为一种极具前景的多功能碳纳米材料,因其对可见光的强吸收、良好的光学性能以及可调的能隙结构,在光催化领域成为热门研究课题。近年来,人们致力于通过将碳点与其他催化剂结合形成复合物来提高其催化性能。除此之外,碳点在多个领域也展现出良好的催化性能。然而,专注于碳点作为单一组分光催化剂的光催化性能及机制的综述较为缺乏。深入了解碳点的内在结构特征及调控策略对于进一步推进其光催化应用至关重要。本综述系统地总结了碳点的固有结构特征、性能提升策略(包括元素掺杂和表面功能化)以及其作为单一组分催化剂在各种光催化反应中的应用。

Abstract:

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.
