Abstract:Carbon materials are a class of magical materials. Carbon atoms can be hybridized by sp, sp2 or sp3 to construct carbon materials with different microstructures. The allotropes of carbon that have been found so far are graphite, diamond, fullerene, carbon nanotube, carbon nanoring, graphene and graphdiyne. Due to the excellent properties and broad application prospects, the discoverers of fullerene and graphene have been honored by the Nobel Prize in 1996 and 2010, respectively. Since carbon nanorings have special structure, excellent mechanical strength with unique physical and chemistry properties, they have attracted much attention. Initially people have carried out some theoretical calculations to predict the properties of carbon nanorings, Up to now, carbon nanorings with different sizes have been successfully prepared through chemical vapor deposition, laser irradiation, ultrasonic self-assembly, etc., and their properties and applications have also been explored. This paper summarizes the growth mechanism, controllable synthesis, properties and applications of carbon nanorings for nearly 30 years. Furthermore, suggestions and prospects for the large-scale synthesis and application of carbon nanorings are presented.
