The oxidation of trichloroethylene over different mixed oxides derived from hydrotalcites

- The activity of the Me2+(Fe/Al) mixed oxides follow this trend: Co > Ni > Mg.
- The substitution of Fe by Al in the mixed oxide improves the catalytic activity.
- There is a strong Co-Al interaction increasing the catalyst acidity and activity.
- CoAl mixed oxides are stable, active and selective catalysts for the oxidation of TCE.
