PPy nanocomposites have been extensively reported in the literatme [261-267]. In the case of inorganic nanoparticles/conducting polymer nanocomposites, various inorganic nanomaterials including silica, palladium, platinum, and maghemite have been formed via inclusion techniques using both chemical and electrochemical approaches [261]. Multifunctional nanocomposites could be fabricated by the judicious choice of synthetic techniques and inorganic materials. 

Environmental Applications of Multifunctional Nanocomposite Catalytic Materials Issues with Catalyst Combinations... 

This suggests some (neutralisation) interactions between the acidic zeolite and the basic BaO which decreases both trapping capacities through the removal of (acidic and basic) surface sites and also decreases the SCR-NH activity, since the concentration and nature of acidic sites is also important in the mechanism of this reaction. This is a clear example of one of the issues involved in generating a multifunctional nanocomposite material in order to work in a range of conditions, i.e. undesired interactions on the surface of the catalyst itself decreasing the efficiency of each component within the composite material. 

The final example of using multifunctional nanocomposite to promote different reactions comes from the field of green catalysis rather than the environmental catalysis discussed to this point. 

Chapter 1 discloses the environmental applications of multifunctional nanocomposite catalytic materials, the preparation of various combinations of materials with two or more distinct catalytic functionalities and application of these in three different cases which are relevant to environmental and sustainable catalysis viz. (i) coupling NO storage systems with urea hydrolysis and selective catalytic reduction (SCR) catalysts, (ii) constructing a material that would act as a four-way catalyst, and (iii) studies on the generation of a material to promote selective oxidation of an organic molecule using synthesized in situ from H /O mixtures. This is an example of an attempt to couple two heterogeneously catalyzed reactions (in an atom efficient and clean manner) to replace other reactions that would be considered environmentally troublesome. 

Compositematerialcontainingatleastonephasewithconstituentsofl-lOOmn in size can be termed nanocomposites. Nanoparticles commonly used in the nanocomposite include single-walled carbon nanotube (SWCNT), double-walled carbon nanotube (DWCNT), multi-walled carbon nanotubes (MWCNT), carbon nanofiber (CNF), graphite nanoplatelet (GNP), mont-morillonite (MMT), nanoclay and polyhedral oligomeric silsesquioxanes (POSS). Other nanoparticles, such as SiOj, AljOj, TiOj and nanosilica are also used in the nanocomposite. The potential benefits of the nanoparticles for structural and multifunctional nanocomposites are sunamarized below.
