| description | Cupreous oxide/boehmite system was prepared by electrochemical alternating current oxidation of copper and aluminium. Both artificial carbonization of electrolysis product by carbon dioxide passing through suspension and spontaneous air carbonization were carried out to copper-aluminum layered double hydroxide (Cu-Al/LDH) preparation. It is not possible to produce Cu-Al/LDH by artificial carbonization because of copper carbonate hydroxide obtaining. At spontaneous air carbonization the aging of electrolysis product in electrolyte (sodium chloride) solution, regular stirring and the maximal interfacial area contribute to highly intensive phase transformation, but results in electrolysis product interaction with electrolyte ions to copper chloride hydroxide formation. Decrease of electrolyte solution concentration delays phase transformation, however, prevents from electrolysis product interaction with electrolyte ions: copper-aluminum carbonate hydroxide is the only copper-containing compound. |
