Using hydroxylamine as a reducer to prepare N-doped graphene hydrogels used in high-performance energy storage

Non-covalent functionalization of reduced graphene oxide using sulfanilic acid azocromotrop and its application as a supercapacitor electrode material

“…3(b), which was consistent with the FT-IR results. 23,[40][41][42][43] The S 2p and N 1s spectra of SAC-RGO are represented in Fig. 3(c).…”

Effect of hydrothermal reaction time and alkaline conditions on the electrochemical properties of reduced graphene oxide

“…7c, broad peak just before the major one at 4nm). The micropores in this sample, probably attributed to defects on A c c e p t e d M a n u s c r i p t 14 the rGO flake that were generated by K 2 CO 3 treatment, exhibit a width of 1.4 nm. As showed in Fig.…”

“…These sheets can be easily surface modified [4] or functionalized through covalent grafting [5][6]. Once GtO is exfoliated, it can be converted into reduced graphene oxide (rGO) [7] by a variety of methods, such as: a) chemical by employing reducing agents like hydrazine hydrate [8][9][10], NaBH 4 [11][12], urea [13], hydroxylamine [14], pyrrole [15], etc., b) microwaves [16][17][18][19], c) thermal annealing [20][21][22][23][24][25] and d) hydrothermal processing [26][27][28][29][30][31]. rGO has attracted intensive attention mainly because it can be cheaply produced on a large scale from GtO.…”

Petal-shaped poly(3,4-ethylenedioxythiophene)/sodium dodecyl sulfate-graphene oxide intercalation composites for high-performance electrochemical energy storage

“…This value is larger than the d-spacing (0.335 nm) of pristine graphite (2q ¼ 26.6 ) as a result of the introduction of oxygenated functional groups [41]. Furthermore, the broad peak at 21.4 indicates that the GO sheets exhibit some aggregations [42]. For the PEDOT pattern, a broad diffraction peak at 2q ¼ 26 is observed, indicating that the PEDOT is amorphous in nature [43].…”
