Decoration of graphene oxide with copper selenide in supercritical carbon dioxide medium as a novel approach for electrochemical sensing of eugenol in various samples

The decoration of reduced graphene oxide with copper selenide ([email protected]) was carried out under supercritical carbon dioxide (sc-CO2). Sc-CO2 has gas-like diffusivity, extremely low viscosity, and excellent penetration ability, allowing it to reduce graphene oxide (GO) and debundle reduced graphene oxide (rGO) sheets to disperse CuSe nanoparticles in between. The synthesized nanomaterials, GO, rGO, [email protected] and [email protected]...
