Special Issue Information

Dear Colleagues,

Carbon nanomaterials have attracted increasing attention in the last few decades, and they and are being extensively investigated due to their peculiar properties. Carbon nanomaterials are well-suited for a wide number of applications thanks to their remarkable physicochemical, optical, electronic, and electrical properties. The typical functional applications of carbon nanomaterials span from energy storage and conversion and catalysis support to the production of advanced sensors, drug delivery, and many more.

We are launching this Special Issue with the aim of further exploring the synthesis methods and functional applications of different carbon nanomaterials. This Special Issue covers the latest progress in the production of different nanocarbon materials (nanodiamonds, fullerenes, nanotubes, graphene, carbon dots, soot particles, etc.), with a special focus on high-temperature routes and particularly flame synthesis. Studies on all the different ex situ and in situ characterization techniques for structure control, property analysis, and functional applications of these nanomaterials are welcome.

Full papers, communications, and reviews covering these subjects are welcome.

This study developed a highly facile method to synthesize Zn-decorated and nitrogen-doped hierarchical porous carbons for carbon dioxide (CO2) adsorption. Zeolitic imidazolate framework-8 (ZIF-8) was used as the raw material, which was subjected to a thermal treatment to obtain ZIF-8-derived carbons (ZDCs) in order to develop nanocarbons with a stable framework structure, a high CO2 adsorption capacity, and high selectivity under normal pressure. The crystallinity evolution of the samples changed from the typical ZIF-8 structure to having features of graphite carbons upon heating. The average particle sizes of the products were between 34 and 105 nm, and the specific surface areas ranged from 618 to 1862 m2/g. The nitrogen and zinc contents gradually decreased with increasing carbonization temperatures, but the changes in the distributions of the functional groups were different. The interactions between CO2 and the ZDCs were significantly enhanced, resulting in a higher isosteric heat of adsorption. The ZIF-8 carbonized at 1123 K exhibited the highest CO2 uptake, i.e., 3.57 mmol/g at 298 K and 101.3 kPa, while higher CO2 uptakes at 15 kPa occurred on the ZIF-8 carbonized at 923 and 1023 K due to their high isosteric heat of adsorption of CO2. The higher adsorption selectivity of Z8-650 for CO2 over N2 may be due to its higher V<0.7nm/Vmi ratio and nitrogen and zinc contents. Consequently, the micropore area ratio and surface functional groups primarily determined the CO2 adsorption capacity at 15 kPa. In addition, an appropriate metal Zn to Zn2+ ratio may have a positive effect on CO2 adsorption. On the other hand, the ultramicropore volume ratio, micropore volume ratio, micropore area, and SSA played more significant roles at 101.3 kPa of pressure. Full article

The investigation of new composite materials possessing low weight but not at the expense of their mechanical performance is of great interest in terms of reducing energy consumption in many industrial applications. This study is focused on the nanomechanical characterization of high-density polyethylene (HDPE)-based composite specimens modified with equal loadings of graphene nanoplatelets (GNPs) and/or multiwall carbon nanotubes (MWCNTs). Quasi-static nanoindentation analysis revealed the impact of the carbon nanofillers on the receiving of nanocomposites with higher nanohardness and reduced modulus of elasticity, reaching values of 0.146 GPa and 3.57 GPa, respectively. The role of the indentation size effect in elastic polymer matrix was assessed by applying three distinct peak forces. Nanoscratch experiments depicted the tribological behavior of the composite samples and inferred the influence of the carbon nanofillers on the values of the coefficient of friction (COF). It seems that the incorporation of 4 wt% GNPs in the polymer structure improves the scratch resistance of the material, resulting in a higher value of the exerted lateral force and therefore leading to the detection of a higher coefficient of friction at scratch of 0.401. A considerable pile-up response of the scratched polymer specimens was observed by means of in-situ SPM imaging of the tested surface sample area. The sway of the carbon nanoparticles on the composite pile-up behavior and the effect of the pile-up on the measured friction coefficients have been explored. Full article
