Special Issue Information

Dear Colleagues,

The surface chemistry of graphene and graphene oxide (GO) is a fascinating field of research, and one whose development is required to realise the great potential of graphene. Indeed, much effort has been and continues to be devoted to the functionalization of graphene and its derivatives. One of the reasons for this endeavor is that graphene in its pristine form is both inert to reaction and a zero-band gap conductor, which lowers its competitiveness for applications such as sensors and semiconductors. The strategies developed include, amongst others, covalent and non-covalent functionalization with organic and inorganic molecules, as well as band gap opening of graphene by doping, intercalation, and striping. In general, any application of graphene and GO will undoubtedly benefit from the controlled synthesis of defined derivatives. Although, at present, the full potential of graphene derivatives has not yet been exploited, multidisciplinary collaboration of researchers is expected to drive technology forward. Many questions remain in this field of research. For example, while in the chemical synthesis of any new compound, isolation and unambiguous structural characterization are key steps, these are very difficult goals in the case of graphene. This is due to the polydispersity, polyfunctionality and often poor solubility of the derivatives prepared. Indeed, classical methods used by synthetic chemists for decades to isolate and characterize new molecules have a limited applicability in the case of graphene and GO. Therefore, in addition to the development of successful methodologies for the functionalization of graphene and GO, new analytical tools for a satisfactory characterization of structure have to be elaborated and applied to these materials.

It is my pleasure to invite you to submit a manuscript for this Special Issue whose objective is to create a collection of papers addressing critical aspects and the latest developments in the field of graphene and GO chemistry. Full papers, short communications, and reviews are welcome.

Recently, graphene oxide (GO) has been largely investigated as a potential adsorbent towards dyes. However, the major obstacle to its full employment is linked to its natural powder consistence, which greatly complexifies the operations of recovery and reuse. With the aim to overcome this issue, the present work reports on the design of GO-modified carbon nanotubes buckypapers (BPs), in which the main component, GO, is entirely entrapped in the BP grid generated by CNTs for the double purpose of (a) increasing adsorption performance of GO-BPs and (b) ensure a fast process of regeneration and reuse. Adsorption experiments were performed towards several dyes: Acid Blue 29 (AB29), Crystal Violet (CV), Eosyn Y (EY), Malachite Green (MG), and Rhodamine B (RB) (Ci = 50 ppm, pH = 6). Results demonstrated that adsorption is strictly dependent on the charge occurring both on GO-BP and dye surfaces, observing great adsorption capacities towards MG (493.44 mg g−1), RB (467.35 mg g−1), and CV (374.53 mg g−1), due to the best coupling of dye cationic form with negative GO-BP surface. Adsorption isotherms revealed that dyes capture onto GO-BPs is thermodynamically favored (ΔG < 0), becoming more negative at 313 K. Kinetic studies evidenced that the process can be described through a pseudo-first-order model, with MG, RB, and CV exhibiting the highest values of k1. In view of these results, the following trend in GO-BP adsorption performance has been derived: MG ≈ RB > CV > AB29 > EY. Full article
