摘要: An original concept based on carbon replica method and adapted organic/inorganic (O/I) hybrid layered double hydroxide (LDH) assembly is used to impart resulting composites replicas with interesting electrochemical properties. Thanks the isomorphous cation substitution possible within LDH layers, a series of O/I materials are prepared using emulsifier 2-acrylamido-2-methyl-1-propanesulfonate acid (AMPS) as source Zn2Al, Co2Al0.5Fe0.5 Ni2Al framework container. The process carbonization leaching characterized by in situ X-ray diffractometry, Raman spectroscopy, pore formation nitrogen adsorption. According carbonization/acid-leaching procedure, behavior various aqueous electrolytes, four salts, including 1.0 M NaNO3, 0.5 Na2SO4, 1 Na2SO3, 6 KOH means cyclic voltammetry, galvanostatic mode, complex impedance spectroscopy.
