Carbon black-intercalated reduced graphene oxide electrode with graphene oxide separator for high-performance supercapacitor [PDF]

open access: yesJournal of Nanostructures, 2019
We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using ...

Synthesis of Reduced Graphene Oxide-Bentonite Composite and Its Application as a Lead(II) Ion Adsorbent

open access: yesIndonesian Journal of Chemistry, 2023
The use of reduced graphene oxide (rGO) as an adsorbent has challenges to overcome. Although rGO has a large surface area, its solubility in water is very low.

Efeito da variação de parâmetros reacionais na preparação de grafeno via oxidação e redução do grafite

open access: yesQuímica Nova, 2014
This work shows the influence of several reactional parameters for obtaining graphene through successive steps of oxidation and exfoliation of bulk graphite (resulting in graphene oxide), followed by chemical reduction. The results showed that changes in

Reduced graphene oxide by chemical graphitization [PDF]

open access: yesNature Communications, 2010
Reduced graphene oxides (RG-Os) have attracted considerable interest, given their potential applications in electronic and optoelectronic devices and circuits. However, very little is known regarding the chemically induced reduction method of graphene oxide (G-O) in both solution and gas phases, with the exception of the hydrazine-reducing agent, even ...

Femtosecond Pump-Probe Studies of Reduced Graphene Oxide Thin Films [PDF]

open access: yes, 2010
The dynamics of photocarriers in reduced graphene oxide thin films is studied by using ultrafast pump-probe spectroscopy. Time dependent differential transmissions are measured with sample temperatures ranging from 9 to 300 K.

Atomic Structure of Reduced Graphene Oxide [PDF]

open access: yesNano Letters, 2010
Using high resolution transmission electron microscopy, we identify the specific atomic scale features in chemically derived graphene monolayers that originate from the oxidation-reduction treatment of graphene. The layers are found to comprise defect-free graphene areas with sizes of a few nanometers interspersed with defect areas dominated by ...
