Nanostructured catalysts in vehicle exhaust control systems

Abstract

This chapter gives the general overview of the current progress in application of nanocatalysts for catalytic conversion of toxic admixtures in vehicle exhaust control systems. Nanostructured materials offer broad facility to enhance the catalytic activity of traditional catalysts such as noblemetals, base metal oxides, and perovskites. Many catalysts consist of precious metals in the shape of particles, and decrease of their size leads to reduction of metal consumption. On the other hand, the quantum size effects are able to explain the high chemical activity of the nanostructured catalysts. New types of catalysts based on carbon nanostructures make it possible to upgrade and improve possibilities of the vehicle exhaust control systems.
