Mix the solvent with the surfactant, pour this solution into the product, and then use an ultrasonic probe to mix the compounds and make them available for use. only. Producing reduced graphene oxide by reducing graphene oxide is a very major and critical process as it possesses a large influence on the produced-rGO's quality, and this will determine the closeness that rGO will come to pristine graphene, regarding structure. Using reduced graphene oxide as a transparent electrode is a convenient alternative to other transparent electrodes for these devices. Graphene oxide can also be reduced to yield reduced graphene oxide, which has similar electronic features to graphene. In addition to being a transparent electrode . As reduced graphene oxide does not dissolve or disperse in water, you can use acetone, distilled water, methanol, or ethanol as solvents. Graphene oxide (GO) and reduced graphene oxide (RGO), due to their large active surface areas, can serve as a platform for biological molecule adhesion (both organic and inorganic). Reduced graphene oxide aerogels could also be used as an active electrode for supercapacitors, electrochemical devices for storing electric energy on the surface of highly porous materials with organic/inorganic electrolyte.
