Energetically efficient and electrochemically tuneable exfoliation of graphite: process monitoring and product characterization

Graphene-polyvinyl alcohol polymer based saturable absorption at 2000 nm region

“…In their work, the process requires simple apparatus which include graphite electrodes, electrolyte and DC power supply. The same method of processing has been recorded in a work by Parvez et al [6], Raj et al [7], Bhullar and Liu [8] and Ljubek et al [9] which indicate that this method of graphene synthesis are widely accepted due to its practicality and low-cost. In saturable absorption, few works have been based on graphene synthesis using  ISSN: 2502-4752 electrochemical exfoliation.…”

Photoelectrocatalytic activity of silicon nanowires decorated with electroless copper nanoparticles and graphene oxide using a plasma jet for removal of methyl orange under visible light

“…The improvement of the current response of Si NWs -Cu NPs can be attributed to the presence of the more conductive copper, while the enhancement in Si NWs -Cu NPs -GO can be associated with the particles of GO. 59,60…”

Electrochemical Exfoliation of Graphene Oxide: Unveiling Structural Properties and Electrochemical Performance

“…Furthermore, we observed that below 2 V vs. Ag/AgCl (KCl 3 M) the intercalation step results in yields with low efficiency for the global process and that the current value increases with higher potentials (E E ), indicating an enhancement in SO 2À 4 intercalation at elevated potentials with the resulting increase in the graphite surface area due to the exfoliation of GO flakes, as reported in previous literature. [43][44][45] The method proposed in this study offers several advantages over traditional and other electrochemical methods. It operates under moderate reaction conditions, requires short processing times, is relatively cost-effective, and is environmentally friendly, as it avoids generating toxic or hazardous waste.…”

“…And another two peaks at 289.1 eV and 290.8 eV corresponding to OÀ C=O and π-π* satellite bonds, respectively. [32,44,49] The relative percentages of these carbon species were quantitatively analyzed, and the results are depicted in Figure S9-S10. Notably, the sp 2 peak corresponding to intact graphene structures exhibited prominence across the different treatments, principally when higher intercalationexfoliation potentials were applied with various acid concentrations.…”

“…A peak at 287.8 eV was assigned to carbonyl groups (C=O). And another two peaks at 289.1 eV and 290.8 eV corresponding to O−C=O and π–π* satellite bonds, respectively [32,44,49] . The relative percentages of these carbon species were quantitatively analyzed, and the results are depicted in Figure S9–S10.…”
