Hydroxycarbonate precursors with different Cu/Zn/Co/Al/Cr atomic ratios were prepared by coprecipitation of the metal nitrates with a stoichiometric amount of NaHCO3under controlled conditions of temperature, stirring, and pH. Cu–Zn–Co–Al–Cr

Samples of CuCo mixed oxide with Cu Co = 0.25 to 1.0 (atomic ratio) were prepared by coprecipitation with Na2CO3 and were characterized with TG, DSC, XRD, and XPS. Exothermic DSC peaks were observed at 588 and 808 K for Cu Co = 0.25 , and at 588,

In a previous communication, it was shown that the precipitate obtained from mixed nitrate solution of Cu, Zn, and Al is more or less monophasic in which Al{sup 3+} ions have been incorporated in the aurichalcite (Cu, Zn){sub 5}(CO{sub 3}){sub 2}(OH)
