|Nanomaterials of metal oxides and conducting polymers have been developed for energy storage (supercapacitor), sensor, and photocatalyst applications. They have shown good electrochemical performances but are not satisfactory. Various materials such as graphene and carbon nanotubes have studied to enhance the electrochemical properties owing to their large surface area and high electrical conductivity. Synergistic effects of excellent conductivities of graphene and high electrical properties of metal oxides or polymers have improved the overall electrochemical performances tremendously. In this study, graphene (natural or synthesized), graphene oxide, reduced graphene oxide, highly reduced graphene oxide have been tested for improving performances as a super capacitor, sensor, and photocatalyst. Other methods have also been used such as doping of graphene with nitrogen or sulfur, using metal sulfides instead of metal oxides, and using highly porous materials as substrates. In the synthesis of these materials, a cleaner technology has been employed.|
