Nanoporous carbon synthesized from grass for removal and recovery of hexavalent chromium
Shahin A. Pathan, Nancy S. Pandita 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 2 10-18 (9 pages)
Nanoporous carbon structures were synthesized by pyrolysis of grass as carbon precursor. The synthesized carbon has high surface area and pore volume. The carbon products were acid functionalized and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer?Emmett?Teller, transmission electron microscopy, and Energy Dispersive X-ray microanalysis. Acid functionalized nanoporous carbon was explored for use in removal of toxic Cr(VI) ions from aqueous media. An... -
KOH-activated graphite nanofibers as CO2 adsorbents
Hui Yuan, Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 12 99-103 (5 pages)
Porous carbons have attracted much attention for their novel application in gas storage. In this study, porous graphite nano-fiber (PGNFs)-based graphite nano fibers (GNFs) were prepared by KOH activation to act as adsorbents. The GNFs were activated with KOH by changing the GNF/KOH weight ratio from 0 through 5 at 900°C. The effects of the GNF/ KOH weight ratios on the pore structures were also addressed with scanning electron microscope and N2 adsorption/desorption measurements. We found that... -
Carbon rich fly ash and their nanostructures
Numan Salah, Sami S. Habib, Zishan H. Khan, Ahmed Alshahrie, Adnan Memic, Attieh A. Al-ghamdi 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 3 23-31 (9 pages)
Carbon rich fly ash was recently reported to have compositions that are ideal for use as a precursor and catalyst for carbon nanotube growth. This fly ash powder is mostly composed of pure carbon, predominantly present as sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity,... -
Adsorption of lisinopril and chlorpheniramine from aqueous solution on dehydrated and activated carbons
El-Said I. El-Shafey, Haider A. J. Al-Lawati, Wafa S. H. Al-Saidi 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 2 12-22 (11 pages)
Date palm leaflets were used as a precursor to prepare dehydrated carbon (DC) via phosphoric acid treatment at 150°C. DC, acidified with H3PO4, was converted to activated carbon (AC) at 500°C under a nitrogen atmosphere. DC shows very low surface area (6.1 m2/g) while AC possesses very high surface area (829 m2/g). The removal of lisinopril (LIS) and chlorpheniramine (CP) from an aqueous solution was tested at different pH, contact time, concentration, and temperature on both carbons. The... -
A review: methane capture by nanoporous carbon materials for automobiles
Pil-Seon Choi, Ji-Moon Jeong, Yong-Ki Choi, Myung-Seok Kim, Gi-Joo Shin, Soo-Jin Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 3 18-28 (11 pages)
as an important green and economic technology. It is very important to develop highly efficient adsorbents to realize techno-economic systems for CH4 adsorption and storage. In this review, we summarize the nanomaterials being used for CH4 adsorption, which are divided into non-carbonaceous (e.g., zeolites, metal-organic frameworks, and porous polymers) and carbonaceous materials (e.g., activated carbons, ordered porous carbons, and activated carbon fibers), with a focus on recent research. -
Photocatalytic performance of graphene/Ag/TiO₂ hybrid nanocomposites
Jong-Ho Lee, In-Ki Kim, Donghwan Cho, Jeong-Il Youn, Young-Jig Kim, Han-Jun Oh 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.4 4 247-254 (8 pages)
To improve photocatalytic efficiency, graphene/Ag/TiO₂ nanotube catalyst was synthesized, and its surface characteristics and photocatalytic activity investigated. For deposition of Ag nanoparticles on the TiO₂ nanotubes, a polymer compound containing CH₃COOAg/poly(Llactide) was utilized, and the silver particles were precipitated by reducing the silver ions during the annealing process. Graphene deposition on the Ag/TiO₂ nanotubes was achieved using an electrophoretic deposition process.... -
Influence of oxidative atmosphere of the electron beam irradiation on cyclization of PAN-based fibers
Hye Kyoung Shin, Mira Park, Hak-Yong Kim, Soo-Jin Park 한국탄소학회 Carbon Letters 3 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 10 219-221 (3 pages)
In order to study the impact of atmosphere during electron beam irradiation (EBI) of polyacrylonitrile (PAN) precursor fibers, the latter were stabilized by EBI in both air and oxygen atmospheres. Gel-fraction determination indicated that EBI-stabilization under an oxygen atmosphere leads to an enhanced cyclization in the PAN fibers. In the Fourier-transform infrared spectroscopy analysis, the PAN fibers stabilized by EBI under an oxygen atmosphere exhibited a greater decrease in the peak... -
Bulk graphite: materials and manufacturing process
Sang-Min Lee, Dong-Su Kang and Jea-Seung Roh 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 1 135-146 (12 pages)
Graphite can be classified into natural graphite from mines and artificial graphite. Due to its outstanding properties such as light weight, thermal resistance, electrical conductivity, thermal conductivity, chemical stability, and high-temperature strength, artificial graphite is used across various industries in powder form and bulk form. Artificial graphite of powder form is usually used as anode materials for secondary cells, while artificial graphite of bulk form is used in steelmaking... -
Hydrogen storage capacity of highly porous carbons synthesized from biomass-derived aerogels
Yong-Ki Choi, Soo-Jin Park 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 9 127-131 (5 pages)
In this work, highly porous carbons were prepared by chemical activation of carbonized biomass-derived aerogels. These aerogels were synthesized from watermelon flesh using a hydrothermal reaction. After carbonization, chemical activation was conducted using potassium hydroxide to enhance the specific surface area and microporosity. The micro-structural properties and morphologies were measured by X-ray diffraction and scanning electron microscopy, respectively. The specific surface area and...
