Supplementary Data for Charcoal to Graphene: A Sustainable Route via Electrochemical Exfoliation

Supplementary Data for Charcoal to Graphene: A Sustainable Route via Electrochemical Exfoliation This dataset contains the supplementary experimental data supporting the manuscript on Charcoal to Graphene: A Sustainable Route via Electrochemical Exfoliation. The files include raw and processed data obtained from electrochemical and spectroscopic characterization, as well as image analysis of graphene morphology. Contents: Cyclic Voltammetry (CV) Summary: Processed plots and extracted parameters, summarizing the electrochemical activity of coal-derived graphene. Electrochemical Impedance Spectroscopy (EIS) Summary: Raw data of EIS. Summarized values of charge transfer resistance and double-layer capacitance. Raman Spectroscopy Data: Raw Raman spectral files with D, G, and 2D band information. Graphene Flake Size Analysis: ImageJ-based measurements of graphene flake dimensions. Format: Excel (.xlsx), and Plots (.png, and .jpg) Purpose: To provide transparent, reproducible, and reusable data supporting the conclusions of the study.
