Electron Microscopy as a Powerful Tool to Investigate the Exfoliation of Boron NitrideNanosheets

Electron microscopy of materials undergoing chemical reactions provides knowledge of the underlyingmechanisms. However, the reactions are often complex and cannot be fully resolved usinga single method. As well as characterization of the structural properties of two-dimensional (۲D)materials is very important to optimize their synthesis and application. Here, we present the electronmicroscopy method using field emission scanning electron microscopy (FE-SEM) and transmissionelectron microscopy (TEM) for studying the exfoliation of synthesized boron nitride nanosheets. Collectively,our data reveal that the reaction proceeds via a three-step process which leads to a significantreduction in the dimensions and thickness of the as-obtained nanosheets compared to pristine hBN
