Ammonia and water sorption properties of the mineral-layered nanomaterials used as the catalysts for NOx removal from exhaust gases

In this chapter, the use of pillared clays as catalysts in green oxidation reactions is considered. Several catalytic oxidation reactions have been selected, and special attention is given to the reaction products and to the yields achieved.Keywords PILC · Pillared clays · Green oxidation reactions · Catalysts IntroductionPillared InterLayered Clays (PILCs, in short) are prepared by exchanging the charge-compensating cations present in the interlamellar space of the clays with hydroxy-metal polycations. On calcination, the inserted polycations yield rigid, thermally stable oxide species, which prop the clay layers apart and prevent their collapse. The intercalation and pillaring processes produce the development of a porous structure with the presence of particular surface sites. These solids have been used in catalytic, purification, and sorption-based separation applications.The methods and the mathematical models used in the characterization of the porous structure of PILCs have been presented in a recent review [1]. From this study and all the references cited therein, it is clear that a great interest exists in the microporous structure of PILCs as well as in the effect of their structure on the applications of these materials. In summary, several researchers have suggested a bimodal micropore distribution for the microporous structure developed by the intercalated and the pillared clays, but this suggestion is open to questioning and can contribute to the expansion of this field in the coming years.Interest in the application of PILCs as catalysts has undergone a huge increase over the last few years [1,2]. One of the most studied subjects related to PILCs
