Reduced graphene oxide (Gr) has been synthesized electrochemically on the surface of copper metal at a fixed potential of 1.5 V versus a standard saturated calomel electrode (SCE). The synthesized Gr was then characterized with X-Ray diffraction, thermogravimetric analysis, raman and Fourier transform infrared (FT-IR) spectroscopies.

Graphene-based electrode materials exhibit a high specific capacitance and long charge-discharge cycling life, but the material cost remains high because of the complexity of the graphene manufacturing process. This study employed an electrochemical exfoliation method to prepare graphene in a simple and ecologically friendly procedure. According to research findings, the disordered multi-layer structure of graphene exhibited great purity, porosity, and graphitization.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).
