摘要：
Single-wall carbon nanohorns (SWCNHs)are hollow conical carbon nanomaterials produced by curling a single layer of graphene. SWCNHs cannot exist alone in a normal state,but instead as spherical aggregates formed by thousands of SWCNHs. Due to their excellent electrical and thermal properties,low density,and high specific surface area,SWCNHs are regarded as promising carbon nanomaterials for electrochemical application. SWCNHs are usually prepared by laser ablation,arc discharge,and joule heating methods,and these process do not use metal catalysts,so as to avoid impurity contamination,which broadens the application of SWCNHs. Over the last two decades,SWCNHs have been widely used in supercapacitors,electrochemical sensors,and lithium-ion,solar,fuel,and metal-CO2 batteries. Numerous studies have shown that SWCNH-based electrochemical devices offer high efficiency,stability,and safety. Promoting the industrial production and large-scale application of SWCNHs in the electrochemical field is of great significance to the development of new energy and high-end manufacturing industries in China. This study summarizes the structure,characteristics,and preparation methods of SWCNHs,reviews the research progress of SWCNHs in the field of electrochemistry,and prospects future research directions and development trends of SWCNHs. © 2024 Cailiao Daobaoshe/ Materials Review.
