Special Issue Information

Dear Colleagues,

A wide range of outstanding and novel features of such carbon nanomaterials as graphene, carbon nanotubes, carbon dots and fullerene have attracted the attention of researchers around the world. The covalent and non-covalent functionalization of these structures by various bio- objects, metal oxides, dichalcogenides, different chemical atoms and molecules, etc. provides parameters required for modern electric devices. In particular, unique mechanical properties of carbon nanocomposites make them an essential part of element base for stretchable and transparent electrodes for transistors, lithium-ion batteries and supercapacitors, as well as electrochemical biosensors. Mathematical modeling of carbon nanostructures’ functionalization performed by present-day software helps to achieve the desired configuration of composite that provides optimum mechanical properties; for example, Young modulus, Poisson ratio, fracture strength during strain, crumbling, bending and nanoindentation.

Thus, the main focus of the forthcoming Special Issue “Modeling and Mechanics of Carbon-Based Nanostructures and Electronic Devices” is to present novel research and review articles devoted to modeling the mechanical carbon-based nanostructures and its application in various electronic devices.

In this study, high-surface-area carbon black is used to support PtRu. In order to increase the functional groups on the surface of carbon black and to have a more homogenous dispersed PtRu metal, the surface of carbon black is functionalized by H2O2. PtRu/carbon black is synthesized by the deposition–precipitation method. NaH2PO2 is used as the reducing agent in preparation. These catalysts are characterized by N2 sorption, temperature-programmed desorption, X-ray diffraction, transmission electron microscope, and X-ray photoelectron spectroscopy. The methanol oxidation ability of the catalyst is tested by cyclic voltammetry measurement. Using H2O2 to modify carbon black can increase the amount of functional groups on the surface, thereby increasing the metal dispersion and decreasing metal particle size. NaH2PO2 as a reducing agent can suppress the growth of metal particles. The best modified carbon black catalyst is the one modified with 30% H2O2. The methanol oxidation activity of the catalyst is mainly related to the particle size of PtRu metal, instead of the surface area and conductivity of carbon black. The PtRu catalyst supported by this modified carbon black has very high activity, with an activity reaching 309.5 A/g. Full article
