Abstract

The reaction of n-butyl amine adsorbed on the ternary oxide La2CuO4 has been studied by x-ray photoelectron spectroscopy (XPS), paying special attention to the surface composition. We suggest that n-butyl amine reacting with La2CuO4 reduces CuO to Cu2O. The reaction is confined to the surface because the original composition of the material could be restored after in situ scraping with a stainless steel blade.
