摘要
碳点是零维纳米碳材料的一种典型代表,由碳原子sp^(2)/sp^(3)杂化构成且尺寸通常小于10 nm.碳点独特的尺寸效应赋予其丰富的边缘活性位点和易于功能化调控等特性,在电催化、能源存储与转化等领域表现出广阔的应用前景.基于此,揭示碳点的形成机制及阐明其结构与性能的基本规律,以指导碳点的合成并获得优异的催化性能具有重要意义.本文在介绍碳点制备及调控策略的基础上,结合理论研究分析了碳点类催化材料活性的来源,并着重评述了碳点在电化学领域的最新应用进展,探讨了功能碳点材料未来发展的机遇与挑战.
As a typical zero-dimensional carbon material,carbon dots(CDs)with particle size smaller than 10 nm are composed by sp^(2)/sp^(3) hybridization of carbon atoms.Owing to their unique physicochemical structures,CDs have many features,such as rich edge sites and accessibility for functional modification,which endow themselves wide applications in electrocatalysis and energy storage/conversion.Based on this,it is of great significance to reveal the formation mechanism of CDs and clarify the structure-property relationship,which is helpful in guiding the synthesis of CDs and then obtain excellent catalytic performance.Therefore,based on the introduction of preparation and regulation strategies of CDs,this paper analyzes the activity origin of CDs-based catalytic materials by combining with theoretical investigations and more importantly,reviews the recent progress of CDs applications in electrochemistry and discusses the opportunities and challenges for the future development of functional CDs materials.
