Issues like trap materials selection, catalyst development, catalytic vs. non-catalytic trap performance are addressed.
Specific highlights of the research in catalytic materials developed at Politecnico di Torino in the framework of EU projects will also be provided.
Wall-flow filters (materials: partially sintered SiC or cordierite grains; pore size: 10 μm) are very efficient (>90%) since they are based on a shallow-bed filtration mechanism, whereas foam (materials: zirconiatoughened-alumina or -mullite, SiC; pore size: 100-400 μm) and fibre filters (materials: dopedalumina; fibre size: 10 μm) are somehow less efficient as a consequence of the deep filtration mechanism they enable.

When two or more materials with different properties are combined together, they form a composite material [2-3].
The properties of composite materials, in general, are superior in many respects to those of the individual constituents.
This has provided the main motivation for the research and development of composite materials.
In our research, amphoteric vinyl-polymer/ZnO nano composite (PDM/ZnO) was prepared using DMDAAC, acrylic acid, 2-hydroxyethyl acrylate, acrylamide as raw materials.
The resultant leather samples were put into an air conditioner for 48 h, and the tensile and tearing strength of the leather were tested with a GT-U55 functional materials examination machine made by Taiwan High Iron Science and Technology Stock Company.
