Pt/CuZnAl mixed oxides for the catalytic reduction of nitrates in water: Study of the incidence of the Cu/Zn atomic ratio

Résumé

1%wt Pt was impregnated on CuZnAl calcined hydrotalcite-type precursors with three Cu/Zn atomic ratios (2, 1 and 0.5). The calcined hydrotalcites and the Pt impregnated materials were characterized by: XRD, BET, TGA, and TPR. These materials were tested as catalysts for the nitrate reduction in water, to study the role of the Cu/Zn atomic ratio in the conversion and selectivity of the reaction. The different Cu/Zn atomic ratios led to different catalytic behaviours. In addition, support activity and adsorptive tests were performed.
