Three-dimensional porous graphene materials for environmental applications
Muruganantham Rethinasabapathy, Sung-Min Kang, Sung-Chan Jang, Yun Suk Huh 한국탄소학회 Carbon Letters 13 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 1 1-13 (13 pages)
Porous materials play a vital role in science and technology. The ability to 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... -
Facile preparation of self-assembled wool-based graphene hydrogels by electron beam irradiation
Mira Park, Bishweshwar Pant, Jawun Choi, Yong Wan Park, Chohye Lee, Hye Kyoung Shin, Soo-Jin Park4, Hak-Yong Kim 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 11 136-141 (6 pages)
Three dimensional self-assembled graphene hydrogels were easily fabricated by electron beam irradiation (EBI) using an aqueous solution of wool/poly(vinyl alcohol) and graphene oxide (GO). After exposure to various levels of EBI radiation, the highly porous, self-assembled, wool-based graphene hydrogels were characterized using scanning electron microscopy and Fourier-transform infrared spectroscopy; to determine the gel fraction, degree of swelling, gel strength, kinetics-of-swelling analyses... -
Sorption behavior of slightly reduced, three-dimensionally macroporous graphene oxides for physical loading of oils and organic solvents
Ho Seok Park, Sung Oong Kang 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 4 24-29 (6 pages)
High pollutant-loading capacities (up to 319 times its own weight) are achieved by three-dimensional (3D) macroporous, slightly reduced graphene oxide (srGO) sorbents, which are prepared through ice-templating and consecutive thermal reduction. The reduction of the srGO is readily controlled by heating time under a mild condition (at 1 10?2 Torr and 200°C). The saturated sorption capacity of the hydrophilic srGO sorbent (thermally reduced for 1 h) could not be improved further even though the... -
Comparative electrochemical study of sulphonated polysulphone binded graphene oxide supercapacitor in two electrolytes
Harish Mudila, M.G.H. Zaidi, Sweta Rana, S. Alam 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 7 43-48 (6 pages)
Sulphonated polysulphone (SPS) has been synthesized and subsequently applied as binder for graphene oxide (GO)-based electrodes for development of electrochemical supercapacitors. Electrochemical performance of the electrode was investigated using cyclic voltammetry in 1M Na2SO4 and 1M KOH solution. The fabricated supercapacitors gave a specific capacitance of 161.6 and 216.8 F/g with 215.4 W/kg and 450 W/kg of power density, in 1M Na2SO4 and 1M KOH solutions, respectively. This suggests that... -
Hierarchical porous carbon nanofibers via electrospinning
Aikifa Raza, Jiaqi Wang, Shan Yang, Yang Si, Bin Ding 한국탄소학회 Carbon Letters 14 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.1 1 1-14 (14 pages)
Carbon nanofibers (CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a... -
