Magnesium-iron mixed oxides with Mg/Fe molar ratios 1, 3, and 6 were prepared from hydrotalcite-type precursors. Microcalorimetric adsorption of NH 3 and CO 2 showed that the surface acidity and basicity of the mixed oxides after calcination at 673 K are similar despite the different Mg/Fe ratios. I
