Synthesis of reduced Graphene Oxide (rGO) using different treatments of Graphene Oxide (GO)

IOP Conference Series: Materials Science and Engineering, 2018
In this work, a combined chemical and mechanical method was used for the production of graphene instead of chemical method only. The use of mechanical sonication was to assists exfoliation graphene oxide (GO) besides the used of chemical reagents. Then, the reduction of GO into graphene was carried out using L-ascorbic acid.

Lithium-storage properties of gallic acid-reduced graphene oxide and silicon-graphene composites [PDF]

, 2016
Graphene oxide (GO) was de-oxygenated using gallic acid under mild conditions to prepare reduced graphene oxide (RGO). The resultant RGO showed a lithium-ion storage capacity of 1280\ua0mA\ua0h\ua0g at a current density of 200\ua0mA\ua0g after 350 cycles

Making Graphene Luminescent by Oxygen Plasma Treatment [PDF]

, 2009
We show that strong photoluminescence (PL) can be induced in single-layer graphene using an oxygen plasma treatment. The PL is spatially uniform across the flakes and connected to elastic scattering spectra distinctly different from those of gapless ...

Synthesis and characterization of graphene oxide (GO) and reduced graphene oxide (RGO) supercapacitors

, 2023
Os supercapacitores são dispositivos que acumulam energia elétrica e apresentam ciclo de vida longo, alta potência de densidade e baixo peso. Apesar dessas propriedades, eles possuem baixa capacitância e densidade de energia em comparação com outros dispositivos. Para avançar na aplicabilidade dos supercapacitores, é necessário desenvolver materiais de
