Abstract
We have prepared zinc-aluminum or magnesium-aluminum layered double hydroxide(LDH) thin films by the sol-gel method with hot water treatment. In this study, nickel-aluminum LDH thin film, which can be applied to electrodes in electrochemical devices, was prepared by using similar process. Ni-Al oxide-based amorphous thin films were prepared by dip-coating on soda lime glass substrates using sol from Al(O-sec-C4H9)3 and Ni(NO3)2, and with heat-treatment at 400 degree C in air. After hot water treatment in NaOH aqueous solution (pH8) at 100 degree C, Ni-Al LDH was formed on the surface of the thin film.
