Abstract
Two-dimensional (2D) materials have gained great importance since the discovery of graphene. Of these several 2D materials, PbFCl and BaFCl, have not been exploited for electrochemical applications. Herein, we have prepared single and few-layered nanosheets of PbFCl and BaFCl by exfoliation through ultrasonication in different solvents such as water, dimethylformamide and N-methyl-2-pyrrolidone. The Hansen-Solubility-Parameters of the solvents played an important role in exfoliation of bulk phase of PbFCl and BaFCl. These materials were studied for supercapacitor properties by means of cyclic voltammetry (CV) curves, galvanostatic charge–discharge (GCD) curves and electrochemical impedance spectroscopy (EIS). Exfoliated 1–2 layered PbFCl exhibits a high-specific capacitance of 158 F g−1 at a scan rate of 10 mV s−1.
