Covalent double functionalization of graphene oxide for proton conductive and redox-active functions

Stepwise rapid electrolytic synthesis of graphene oxide for efficient adsorption of organic pollutants

“…35 Yuta Nishina et al have conducted extensive research on the preparation and applications of GO for coating, photocatalysis and composite materials. [36][37][38][39][40][41][42] In order to prepare heavily oxidized GO, they used H 2 SO 4 as the electrolyte to conduct the electrochemical exfoliation of graphite powder. The whole preparation process took 90 min, and most of the GO sheets had multilayers with an oxygen content of ca.…”

Functional groups in graphene oxide

“…More specifically, GO can be regulated not only by its original functionalities but also by pre-modification to adopt more reactive groups for further derivatisation. 15,16 This has prompted a significant interest in selective modification via different strategies through the targeted surface functional group. The original surface functionalities can be replaced with other functional molecules or adopted to react with additional reactive moieties for tethering various molecules, including polymers, ionic liquid, and biomolecules.…”

Site‐selective Mono‐ and Bifunctionalization of Graphene Oxide: Screening Nanocatalysts for Organophosphate Degradation

“…[8] Additionally, the band attributed to C-OH (1395 cm À 1 ) which is very discrete for GO, is more pronounced for GOSH, probably due to the epoxide ring opening that generates extra CÀ OH groups. [15] The bands around 2920 were attributed to the CÀ H modes of methylene on GO. [14a] For the monofunctionalized GOIMZ via the carboxylic acid groups, which was reported previously, [8,10] the main bands confirming functionalization are at 3270 and 1630 cm À 1 , attributed to the NÀ H and C=O of amide, in addition to the other CÀ N and NÀ H bands cited above.…”
