| 1 | Annealing temperature dependent catalytic water oxidation activity of iron oxyhydroxide thin films显示文摘Nanostructured iron oxyhydroxide(Fe OOH) thin films have been synthesized using an electrodeposition method on a nickel foam(NF) substrate and effect of air annealing temperature on the catalytic performance is studied. The as-deposited and annealed thin films were characterized by X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS), field emission scanning electron microscopy(FE-SEM) and linear sweep voltammetry(LSV) to determine their structural, morphological, compositional and electrochemical properties, respectively. The as-deposited nanostructured amorphous Fe OOH thin film is converted into a polycrystalline Fe_2O_3 with hematite crystal structure at a high temperature. The Fe OOH thin film acts as an efficient electrocatalyst for the oxygen evolution reaction(OER) in an alkaline 1 M KOH electrolyte. The film annealed at 200 °C shows high catalytic activity with an onset overpotential of 240 m V with a smaller Tafel slope of 48 m V/dec. Additionally, it needs an overpotential of 290 mV to the drive the current density of 10 m A/cm^2 and shows good stability in the 1 M KOH electrolyte solution. | P.T.Babar B.S.Pawar A.C.Lokhande M.G.Gang J.S.Jang M.P.Suryawanshi S.M.Pawar Jin Hyeok Kim | 2017 | Journal of Energy Chemistry2017，26，4： | 4 |
| 2 | Vertically aligned NiS nano-flakes derived from hydrothermally prepared Ni(OH)2 for high performance supercapacitor显示文摘In present work,the vertically aligned Ni S nano-flakes composed thin film is prepared by anionic exchange process in which hydrothermally prepared Ni(OH)_2is used as a parent thin film and Na_2S as a sulfide ion source.This synthesis process produced fully transformed and shape-controlled nano-flakes of Ni S from nano-flowers of Ni(OH)_2.The electrochemical supercapacitor properties of Ni S electrode are studied with cyclic voltammetry(CV),galvonostatic charge discharge(GCD)and electrochemical impedance spectroscopy(EIS)techniques.Highly porous surface area(85 m^2/g)of Ni S nano-flakes makes large material contribution in electrochemical reaction stretching specific capacitance(C_s)of 880 F/g at scan rate of 5 m V/s and 90%electrochemical stability up to 4000 CV cycles in 2 M KOH electrolyte.Further,the flexible solid-state symmetric supercapacitor device(Ni S/PVA–Li ClO_4/Ni S)has been fabricated using Ni S electrodes with polyvinyl alcohol(PVA)–lithium perchlorate(Li ClO_4)gel electrolyte.The Ni S/PVA–Li ClO_4/Ni S device exhibits specific capacitance of 56 F/g with specific energy of 14.98 Wh/kg and excellent cycling stability after 2000 cycles.In addition,the Ni S/PVA–Li ClO_4/Ni S device demonstrates illumination of red light emitting diode(LED)for 60 s,which confirms the practical applicability of Ni S/PVA–Li ClO_4/Ni S device in energy storage. | A.M.Patil A.C.Lokhande P.A.Shinde J.H.Kim C.D.Lokhande | 2018 | Journal of Energy Chemistry2018，27，3： | 4 |
