Special Issue Information

Dear Colleagues,

Starting in ancient times, when carbons were used as wound powder, through the last century, the discovery of nanostructured carbons as e.g., fullerenes, nanotubes, and graphene—an exponential advance in the science involving nanocarbons—has attracted a great deal of attention from the research community. These materials, which last for years, offer the promise of “properties-by-design” toward numerous, everyday practical applications, from electronics to medicine. Due to their remarkable properties, such as high stability and the ability to formulate different compounds due to various hybridizations, carbon nanomaterials are a topic of scientific interest in several fields of research.

The present Special Issue will focus on the most recent advances in the research on novel carbons and their wide applications. Topics related to all kind of carbonaceous nanomaterials, such as nanodiamond, graphite and graphene oxide, graphene and its derivatives, fullerenes, nano-onions, nanohorns, and nanotubes harnessed in all kinds of catalysis including electro- and photocatalysis, are welcome.

I invite scholars involved in theoretical studies, synthesis and characterization methods, physicochemical properties, engineering and applications, and other research areas to contribute original research papers, as well as review articles, to this Special Issue in order to give the readers of Nanomaterials a new perspective on these versatile and useful materials.

Molybdenum disulfide (MoS2) can be an excellent candidate for being combined with carbon nanomaterials to obtain new hybrid nanostructures with outstanding properties, including higher catalytic activity. The aim of the conducted research was to develop the novel production method of hybrid nanostructures formed from MoS2 and graphene oxide (GO). The nanostructures were synthesized in different weight ratios and in two types of reactors (i.e., impinging jet and semi-batch reactors). Physicochemical analysis of the obtained materials was carried out, using various analytical techniques: particle size distribution (PSD), thermogravimetric analysis (TGA), FT-IR spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Due to the potential application of materials based on MoS2 as the catalyst for hydrogen evolution reaction, linear sweep voltammetry (LSV) of the commercial MoS2, synthesized MoS2 and the obtained hybrid nanostructures was performed using a three-electrode system. The results show that the developed synthesis of hybrid MoS2/GO nanostructures in continuous reactors is a novel and facile method for obtaining products with desired properties. The hybrid nanostructures have shown better electrochemical properties and higher onset potentials compared to MoS2 nanoparticles. The results indicate that the addition of carbon nanomaterials during the synthesis improves the activity and stability of the MoS2 nanoparticles. Full article

H2 plasma treatment was performed on carbon-based nonwoven fabrics (c-NFs) in a 900 W microwave plasma-enhanced chemical vapor deposition system at 750 °C and 40 Torr. Consequently, the electromagnetic wave shielding effectiveness (SE) of the c-NFs was significantly enhanced across the operating frequency range of 0.04 to 20.0 GHz. We compared the electromagnetic wave SE of the H2 plasma-treated c-NFs samples with that of native c-NFs samples coated with nano-sized Ag particles. Despite having a lower surface electrical conductivity, H2 plasma-treated c-NFs samples exhibited a considerably higher electromagnetic wave SE than the Ag-coated c-NFs samples, across the relatively high operating frequency range of 7.0 to 20.0 GHz. The carbon component of H2 plasma-treated c-NFs samples increased significantly compared with the oxygen component. The H2 plasma treatment transformed the alcohol-type (C–O–H) compounds formed by carbon-oxygen bonds on the surface of the native c-NFs samples into ether-type (C–O–C) compounds. On the basis of these results, we proposed a mechanism to explain the electromagnetic wave SE enhancement observed in H2 plasma-treated c-NFs. Full article
