Special Issue Information

Dear Colleagues,

The 7th Conference on Carbon Materials for Energy Storage and Environmental Protection (CESEP2017) will be held in Lyon, France, 23–26 October, 2017. The Conference is devoted to the synthesis, functionalization and application of new types of carbon and graphite forms, such as graphene, fullerenes, carbon nanotubes, nanofibers and composites. Such materials have already found many applications in environmental protection, water purification and remediation, gas separation and storage, solar energy conversion and use, green chemistry process, the power industry, electronics, biotechnologies and medicine, e.g., as adsorbents, sensors, catalyst supports, electrodes in energy sources (supercapacitors, batteries, fuel cells), heat storage devices, implants, etc. CESEP’17 conference emphasis is, not only placed on fundamental research, but also on new areas of application.

This Special Issue selects papers from the CESEP2017 conference and covers a very broad scope, from synthesis and functionalization of different forms of carbon materials (graphenes, nanotubes, nanoporous, graphite) to their applications in water purification, gas separation and storage, energy storage and conversion, electronics, biotechnologies, etc.

We invite authors to contribute original research articles, communications, as well as review articles, to this Special Issue.

Numerous adsorbent materials are developed and are able to face specific types of pollution, but none of them can manage the whole pollution. The purpose of this work is to develop a novel hybrid adsorbent, based on chitosan (CS) biopolymer, clay minerals and activated carbon (AC), having complementary adsorption properties and achieving a wide-spectrum water decontamination in a single treatment. Hybrid CS beads, containing dispersed clay and AC, were prepared from dispersions of solid adsorbents in a CS solution and its further coagulation in a basic medium. The porosity and the homogeneity of the hybrid beads were characterized by N2 adsorption at 77 K and Cryo-Scanning Electron Microscopy respectively. The interaction between CS and clay was characterized using X-ray diffraction. Water content and the amount of each adsorbent in the hydrogel beads were determined by thermogravimetric analysis. Such a composite material was still porous and presented a wide adsorption spectrum. As shown by their adsorption kinetics, hydrophobic anionic clofibric acid (CBA) and cationic metoprolol (MTP) were well adsorbed on AC containing beads (21 and 26 mg/g), respectively. Clays containing beads showed interesting adsorption properties towards cationic Zn2+ and MTP. The obtained composite beads were able to adsorb all the pollutant types: Zinc cations, and hydrophobic-charged organic molecules, such as pharmaceutical derivatives (clofibric acid and MTP).

Calcium phosphate and derivatives have been known for decades as bone compatible biomaterials. In this work, the chemical composition, microtexture, and structure of calcium phosphate deposits on carbon cloths were investigated. Three main types of deposits, obtained through variation of current density in using the sono-electrodeposition technique, were elaborated. At low current densities, the deposit consists in a biomimetic, plate-like, carbonated calcium-deficient hydroxyapatite (CDA), likely resulting from the in situ hydrolysis of plate-like octacalcium phosphate (OCP), while at higher current densities the synthesis leads to a needle-like carbonated CDA. At intermediate current densities, a mixture of plate-like and needle-like carbonated CDA is deposited. This established that sono-electrodeposition is a versatile process that allows the coating of the carbon scaffold with biomimetic calcium phosphate while tuning the morphology and chemical composition of the deposited particles, thereby bringing new insights in the development of new biomaterials for bone repair.

An electrical double-layer capacitor (EDLC) is based on the physical adsorption/desorption of electrolyte ions onto the surface of electrodes. Due to its high surface area and other properties, such as electrochemical stability and high electrical conductivity, carbon materials are the most widely used materials for EDLC electrodes. In this work, we study an activated carbon felt obtained from sheep wool felt (ACF’f) as a supercapacitor electrode. The ACF’f was characterized by elemental analysis, scanning electron microscopy (SEM), textural analysis, and X-ray photoelectron spectroscopy (XPS). The electrochemical behaviour of the ACF’f was tested in a two-electrode Swagelok®-type, using acidic and basic aqueous electrolytes. At low current densities, the maximum specific capacitance determined from the charge-discharge curves were 163 F·g−1 and 152 F·g−1, in acidic and basic electrolytes, respectively. The capacitance retention at higher current densities was better in acidic electrolyte while, for both electrolytes, the voltammogram of the sample presents a typical capacitive behaviour, being in accordance with the electrochemical results.

To develop high capacity electrode materials for lithium-ion battery (LIB), dissimilar materials are mixed and, as a result, carbon nanofibers containing silicon (Si) nanoparticles and its components are successfully created by electrospinning method and some heat treatments. Tetraethoxysilane (TEOS) and Si nanoparticles are adopted as additives of carbon nanofibers because of their huge potential for obtaining high capacity. In this research, therefore, we develop TEOS/Si hybrid carbon nanofibers. Consequently, some samples obtain much higher charging/discharging capacity than the theoretical capacity for graphite (372 mAh/g, LiC6) even after second cycle. Full article
