“…Nowadays in typical procedure, graphene oxide can be produced by modified Hummers method. Lee X. J. et al 9 The presence of graphene oxide greatly reduces the electrical conductivity of the material as it binds the free electrons. According to Mohan et al 8 the graphene oxide could be used as a dielectric material for the purpose of energy storage.…”

It is believed that graphene is a next-generation conducting material with the potential to be used for obtaining of electrodes for supercapacitors. The object of the present study is investigation of possibility of obtain low cost and ecofriendly graphene and study of its properties as material for supercapacitor electrodes. A combination of chemical and physical (ultrasound) impacts on the precursor of the initial raw material-graphite (>99%) was applied for the preparation of graphene. The synthesized graphene shows low specific electrical resistance and this makes it a potential electrode coating material for electrochemical energy storage. It was measured four times lower specific electrical resistance for graphene compared to precursor of graphite.

Silver Decorated Reduced Graphene Oxide as Electrocatalyst for Zinc–Air Batteries

et al. 2020

Due to their low cost and very high energy density, zinc-air batteries (ZABs) exhibit high potential for various energy applications. The electrochemical performance of the air-cathode has a decisive impact on the discharge performance of ZABs because the sluggish oxygen reduction reaction (ORR) kinetics increase the overpotential of the air-cathode and hence the performance of ZABs. In this work, reduced graphene oxide decorated with silver nanoparticles (AgNP/rGO) is synthesized using simultaneous reduction of graphene oxide and silver ions. Different amounts of silver loading are examined for the synthesis of AgNP/rGO. The synthesized AgNP/rGO samples are analyzed using a rotating disk electrode in order to investigate ORR activity. Then, the synthesized AgNP/rGO electrocatalyst is applied on a tubular designed zinc-air battery in order to study the performance of the zinc-air battery. Results demonstrate that AgNP/rGO is an efficient and cost-effective ORR electrocatalyst for its practical application in ZABs.

The utilization of nano-and well-ordered carbon materials such as graphene especially in carbonbased electrical devices and in energy storage areas is becoming important in terms of developing economical methods and reducing the dimensions of the electrical devices. These applied carbon materials are mostly originated from fossil sources which are diminishing. Hence, renewable carbon resources are gaining importance. Biomass is the single renewable carbon resource and can be refined to highly ordered carbon materials such as graphene by top to down methods. In this work, industrial tea waste biomass was converted to carbonized material by pyrolysis and refined by some further chemical treatments towards the ordered structured carbon. The newly derived refined carbon material was characterized by Raman, TGA, FTIR, SEM and XRD methods, and its optical and electrical properties were determined. The experimental results showed that the band gap energies of refined carbon derived from tea waste and reduced graphene oxide prepared in this study are in the similar level as 2.375 and 2.264 eV, respectively. Furthermore, the electrical conductivities are at the same stage as 3.16 and 3.28×10 −4 (1/Ω·cm) for reduced graphene oxide and refined carbon. The optically active and electrical conductive refined carbon material from biomass could be a proper carbon in energy related applications in terms of renewable and sustainable processing.
