Nanoparticles of Co-Ce mixed oxides derived from substituted layered double hydroxides have been synthesized, characterized and tested as new catalysts in the process of catalytic reduction of N2O by NH3 in the presence of oxygen. The preliminary results show that high N2O conversions are obtained in a wide range of temperatures: at 673 K the N2O conversion is equal to nearly 50% and reaches a maximum value equal to almost 90% for temperatures higher than 750 K. In comparison, the catalytic sample derived from calcined not substituted hydrotalcite shows a maximum N2O conversion equal to 40%. [ABSTRACT FROM AUTHOR] |
