Infrared spectra investigation of CuO-Al2O3 precursors produced by electrochemical oxidation of copper and aluminum using alternating current

Abstract

Joint electrochemical oxidation of copper and aluminum using alternating current (AC) was performed. The electrolysis products were dried on air (method carbonate) and at the residual pressure of 3-5 kPa (oxide method). Cu-Al layered double hydroxide (Cu-Al/LDH) is formed at air carbonization. Oxide method saves copper (I) oxide. Heat treatment causes the decomposition of LDH to CuO and Al₂O₃ as well as Cu₂O oxidation to CuO. CuO/Al₂O₃ has a number of catalytic applications. Copper-aluminum spinel (CuAl₂O₄) is the product of solid-phase interaction of copper and aluminum oxides. IR-spectra revealed that oxide method provides the boehmite dehydration and metal oxides interaction at lower temperature despite the fact that the poorly crystallized copper (II) oxide is formed at LDH decomposition.
