Special Issue Information

Dear Colleagues,

In recent years, graphene oxide (GO) and reduced graphene oxide (r-GO) have received a great deal of attention as precursors of graphene-like 2D layered nanomaterials. These materials have unique intrinsic physical and chemical properties, in addition to having a large surface area, functionality containing oxygen, good conductivity, and good biocompatibility. For this reason, many experimental studies have been conducted to improve GO and r-GO, and to analyze their possible application fields. Recently, there has been a growing number of intensive studies which address the preparation and characterization of new nanocomposites which integrate GO or r-GO (GO/r-GO) with polymers, inorganic nanoparticles (metal, metal oxide, etc.), or even nanotubes and fullerenes. These nanocomposite materials with novel nanostructures and integrated properties are receiving an increasing interest.

For example, GO/r-GO-based polymer nanocomposites are receiving remarkable interest due to their excellent mechanical, thermal, and electrical properties. GO/r-GO used as nanometric filler embedded in a polymeric matrix enhance the structural, morphological, and functional properties of the composite material. In addition, these materials are suitable for electronic and energy storage applications in the form of polymer–graphene composites.

Nanocomposites based on GO/r-GO and inorganic nanoparticles such as Au, Ag, Pt, etc. have attracted great attention for various applications as catalysts, photocatalysts, electrodes, sensors, substrates for surface-enhanced Raman spectroscopy, and biomedical applications. So, the development of new synthesis methods for GO/r-GO and nanoparticle composites with good control of size and morphology is necessary to obtain interesting devices.

In addition, the combination of GO/r-GO with different dimensions of carbon-based materials has shown superior performance in several cases; for example, a GO/r-GO and fullerenes system produced membranes with excellent structural stability.

In conclusion, the aim of this second edition of Special Issue is to extend our current knowledge about “Advanced Nanocomposites Materials Based on Graphene Oxide/Reduced Graphene Oxide”, and it is our honor and pleasure to invite you to submit a manuscript to the Special Issue. Original research papers, state-of-the-art reviews, communications are welcomed.

In this work, samples of reduced graphene oxide (rGO) were prepared by treating graphite oxide (GrO) with thiourea (TU) and ascorbic acid (AA). Aerogels rGO-TU and rGO-AA were prepared using the freeze-drying method and were analyzed using X-ray diffraction, FTIR and Raman spectroscopy, 1H and 13C NMR, TEM, and SEM-EDS. Based on the NMR, FTIR, SEM-EDS, and TEM data, GO with TU is reduced with simultaneous functionalization of its oxygen-containing groups. According to 1H and 13C NMR data, the reduction of GO occurred simultaneously with an interaction of the amino groups of thiourea with carbonyl groups on the graphene sheets, forming an imine bond. This is evidenced by the appearance of additional signals in the 13C spectrum of GO-TU samples in the region of 140–230 ppm. The Boehm titration method showed that the number of oxygen-containing groups in rGO-TU aerogels decreased by about five times compared to GO. However, thiourea interacts with the GO surface, most likely due to electrostatic interaction and hydrogen bonds. The adsorption capacity of rGO-TU aerogel with respect to methylene blue (MB) after 1440 min was 60.2 mg/g, while for rGO-AA it was 71.4 mg/g. This fact indicates the importance of optimizing GO reduction to increase the number of active sites. Full article
