WebApr 10, 2024 · With its distinct and novel features, pencil graphite (PG)–turned graphene oxide (GO), a new carbon compound, could be used as an electrode in a supercapacitor due to its distinctive and innovative properties. As part of the preliminary investigation, low-cost graphene electrodes that can be made with basic laboratory apparatus were used. WebMar 24, 2024 · The modified graphite pencil electrode, GPE/rGO/Fe 3 O 4, is characterized using cyclic voltammetry. Higher electrochemical surface area is obtained when the GPE is modified with rGO/Fe 3 O 4. Linear scan voltammetry is used to quantify Hb at the surface of the sensor using ferrocene (FC) as an electrochemical amplifier.
