A modification of the chemical synthesis method was developed, which uses a small amount of strong acids, a low oxidation temperature and a short stirring process. X-ray diffraction (XRD) pattern and Fourier transform infrared spectrometry (FTIR) spectra confirmed that rGO was successfully synthesized. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed rGO in sheet form. Based on energy dispersive x-ray spectrometry (EDX), the surface of the prepared rGO sample was dominated by ∼90% of C atoms. Four-point probe measurements showed the electrical conductivity of the prepared rGO sample at 1180 S m-1. Based on the electrochemical impedance spectrometry (EIS) results gives 2.1 Ω charge transfer resistance between the electrode and the electrolyte to the prepared rGO sample. This study provides a new perspective on rGO synthesis using a wet chemical process.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Charge transfer resistance,Electrical conductivity,Electrochemical impedance spectrometry,Energy dispersive X-ray spectrometry,Four-point probe measurements,Fourier transform infrared spectrometry,Oxidation temperature,Reduced graphene oxides (RGO)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Chemical synthesis,Conductivity,Reduced graphene oxide (rGO)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/2053-1591/aa707f[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
