Recent Advances in Catalytic Decomposition of N2O on Noble Metal and Metal Oxide Catalysts

Catalytic decomposition of nitrous oxide (N2O) is one of the most efficient methods for the removal of N2O which is of high greenhouse potential and ozone-depleting property. Recent progress in the decomposition of N2O has been reviewed with the focus on noble meal and metal oxide catalysts. The influence factors, such as catalyst support, preparation method, alkali metal additives and the reaction conditions (including O-2, H2O, SO2, NO and CO2), on the performance of deN(2)O catalysts have been discussed. Finally, future research direction for the catalytic decomposition of N2O is proposed.
