Nitrogen-doped carbon nanosheets with a developed porous structure were prepared from polyurethane foams by hydrothermal carbonization following ZnCl2 chemical activation. Scanning electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, solid state 13C nuclear magnetic resonance (NMR) spectra and X-ray photoelectron spectroscopy were used to characterize the nitrogen-doped carbon nanosheet structure and composition. The removal of Cr(VI) by the N-doped carbon...

one another and confirmed the presence of carbon species in or on the TiO₂ layer, and the XPS data suggested the substitution of titanium in TiO₂ by carbon. Instead of using calcination, PAN pyrolysis was used to control the carbon content, and the mesoporosity was tailored by the applied temperature. The supported TiO₂ nanocrystals prepared by pyrolysis at 300, 350, and 400ºC for 3 h on a stainless steel mesh were actual supported carbon doped TiO₂ nanocrystals. Thus, PAN/DMF/TiCl₄ offers...

Carboxylated multi-wall carbon nanotubes (MWCNTs-COOH) have been used as efficient adsorbents for the removal of picric acid from aqueous solutions under stirring and ultrasound conditions. Batch experiments were conducted to study the influence of the different parameters such as pH, amount of adsorbents, contact time and concentration of picric acid on the adsorption process. The kinetic data were fitted with pseudo-first order, pseudo-secondorder, Elovich and intra-particle diffusion models....

control their pore structures at the atomic, molecular, and nanometer scales enable interactions with atoms, ions and molecules to occur throughout the bulk of the material, for practical applications. Three-dimensional (3D) porous carbon-based materials (e.g., graphene aerogels/hydrogels, sponges and foams) made of graphene or graphene oxide-based networks have attracted considerable attention because they offer low density, high porosity, large surface area, excellent electrical conductivity...

the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as high thermal stability, high thermal/electrical conductivity, low density, high porosity and high specific surface area [4,5]. CFms are suitable materials for applications in phase-change materials, such as in latent heat thermal energy storage and lithium-ion batteries [6-9].

The development of gas separation membranes is currently an active research area because of the rapidly increasing interest in carbon dioxide capture and hydrogen recovery, which are two of the most important solutions for problems related to energy and the environment [1-4]. Polymer membranes show selectivity in the separation of gases due to differences in the permeability of individual gases through the polymer film [3,4]. Even though advantageous in terms of low cost, the segmental...

The objective of this study is the removal of chromium from tannery wastewater by electrosorption on carbon prepared from lignocellulosic natural residue "peach stones' thermally treated. The followed steps for obtaining coal in chronological order were: cleaning, drying, crushing and finally its carbonization at 900°C. The characterization of the carbon material resulted in properties comparable to those of many coals industrially manufactured. The study of the dynamic adsorption of chromium...

Cobalt was electrodeposited onto chemical vapor deposition (CVD) graphene/Si/SiO2 substrates, during different time intervals, using an electrolyte solution containing a low concentration of cobalt sulfate. The intention was to investigate the details of the deposition process (and the dissolution process) and the resulting magnetic properties of the Co deposits on graphene. During and after electrodeposition, in-situ magnetic measurements were performed using an (AGFM). These were followed by...

Phenomena related to global warming have been of particular interest among researchers, strongly encouraging them to identify various methods of adsorbing contributing gases, such as CH4 and CO2 [1,2]. Many adsorbents have been widely proposed and studied to remove greenhouse gases from the atmosphere and protect the environment [3,4]. Carbon-based materials for adsorption are an intriguing subject owing to their very high specific surface area, low weight, and elasticity [5,6]. Among various...

Recently, microbial electrosynthesis (MESs) has been highlighted for the purpose of biological CO2 reduction with simultaneous production of intermediates and value-added chemicals. The bioelectrochemical system (BES), which employs microorganisms and a bacterial community as a biocatalyst, has been developed to convert CO2, a greenhouse gas, into liquid biofuels, such as ethanol and butanol, as well as platform chemicals [1]. Several bacterial species, called cathodophilic microorganisms (e.g.,...
