Abstract: The increasing problem of atmospheric pollution by NOx has resulted in stricter regulations on their emissions. NOx storage/reduction (NSR) is considered as efficient catalytic technology to abate lean-burn NOx. A wide variety of catalysts have been extensively examined for this purpose. The use of metal oxides, hydrotalcites and their derivatives as NOx storage/reduction catalysts has been reviewed. Suitable combination particularly the catalytic redox component and the storage component can lead to improved activity in NOx decomposition and capturing under the lean-rich conditions.
