摘要

本文综述了紫外和可见光吸收分光光度法在碳纳米结构(如石墨烯、碳纳米管及其杂化物等)研究中的应用。结果表明，这种CNSs在紫外-可见光谱区域具有特征吸收带，表面等离子体共振(SPR)峰的强度与它们在悬浮液中的浓度成正比。可以确定，无论碳纳米结构的结构或制备方法如何，碳纳米结构对光的吸收都可以用Lambert-Beer定律来描述。结果表明，紫外可见光谱是一种快速、经济、通用、廉价的CNSs鉴定和定性、定量表征方法。

Use of UV-Vis Spectrophotometry for Characterization of Carbon Nanostructures: a Review

A detailed review of the application of the method of absorption spectrophotometry in the ultraviolet and visible regions for the study of carbon nanostructures (CNSs), such as graphene, carbon nanotubes (CNTs), their hybrids, etc., is presented. It is shown that such CNSs have characteristic absorption bands in the UV-Vis regions of the spectrum, and the intensity of surface plasmon resonance (SPR) peaks is proportional to their concentration in suspensions. It is established that the absorption of light by carbon nanostructures is described by the Lambert–Beer law, regardless of the structure or method of preparation of such systems. It is shown that spectroscopy in the UV-Vis regions is a fast, affordable, universal, and inexpensive method of identification and qualitative and quantitative characterization of CNSs.
