Mg-Al hydrotalcites (Mg/Al molar ratio 3/1) doped with varying amounts of lanthanum were prepared using co-precipitation followed by calcination in order to study the effect of lanthanum on their structure and morphology. Samples were characterized by several methods: XRD, FT-IR, SEM-EDS, LDPSA and MIP. It was found that the addition of lanthanum affects the structure and morphology of the obtained metal oxides derived from Ladoped Mg-Al hydrotalcites, making it effective dopant for (Mg/Al/La)Otype materials, being very promising for various catalytic reactions.
