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

Several Co/Mg/Al layered double hydroxides (LDH) with (Mg2++Co2+)/Al3+=2 and 3 and Mg2+/Co2+ranging from 0 to 4 have been synthesized by coprecipitation at pH=9 and NO−3as main compensating anions. All samples present well-crystallized layered stru
