다결정 Pt/0.1 M $H_2SO_4$수성 전해질 계면에서 중간주파수 구간의 위상이동 변화와 Langmuir흡착등온식 사이의 관계를 교류임피던스 방법 즉 위상이동 방법을 이용하여 연구 조사하였다. 제안된 계면등가회로는 전해질저항($R_S$), Faraday저항$(R_F)$, 흡착유사용량$(C_varphi)$의 등가회로 요소($C_P$)의 직렬접속으로 구성된다 지연되는 위상이동$(varphi)$은 음전위(E) 및 주파수(f)에 따르며, $varphi=-tan^{-1}[1/2{pi}f(R_s+R_F)C_p]$이다. 중간주파수(6Hz)에서 위상이동 변화$(varphi;vs.;E)$는 Langmuir흡착등온식$(... -
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)
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 KOH is a... -
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

Global warming is considered one of the great challenges of the twenty-first century. In order to reduce the ever-increasing amount of methane (CH4) released into the atmosphere, and thus its impact on global climate change, CH4 storage technologies are attracting significant research interest. CH4 storage processes are attracting technological interest, and methane is being applied as an alternative fuel for vehicles. CH4 storage involves many technologies, among which, adsorption processes... -
Enhanced electrocapacitive performance and high power density of polypyrrole/graphene oxide nanocomposites prepared at reduced temperature
Harish Mudila, Varsha Joshi, Sweta Rana, Mohmd. Ghulam Haider Zaidi, Sarfaraz Alam 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 3 171-179 (9 pages)
An attempt was made to investigate the effect of the preparation temperature on the electrocapacitive performance of polypyrrole (PPY)/graphene oxide (GO) nanocomposites (PNCs). For this purpose, a series of PNCs were prepared at various temperatures by the cetyltrimethylammonium bromide-assisted dilute-solution polymerization of pyrrole in presence of GO (wt%) ranging from 1.0 to 4.0 with ferric chloride as an oxidant. The formation of the PNCs was ascertained through Fourier-transform infrared... -
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... -
