Abstract
The structural changes of layered double hydroxides (LDHs), when zinc was partially substituted by copper and aluminum was partially substituted by cerium in the layer of the LDHs matrix was monitored by X-ray diffraction (XRD), while the bulk composition of the studied samples was confirmed by X-ray fluorescence (XRF). The substituted samples preserved the layered structure, but the constrictions of the network appeared as a result of the substitution. After calcination at 850°C for 7 h, well crystallized mixed oxides containing copper and cerium were formed. The results point out that the calcination temperature is important to establish the structural features of the resulting mixtures of mixed oxides.
