Hot Article: NOx removal via cascade reactions using silica and aminoxyls

02 Dec 2010

The design of new materials for gaseous NO_x (NO and NO₂) removal at ambient temperature using organic active sites is reported in this paper from a team from the University of California at Berkeley. The materials consist of unfunctionalised silica and silica modified by immobilized aminoxyls and function via cascade reactions consisting of NO oxidation to NO₂ and NO₂ adsorption.The application of cascade reactions is an emerging research area that spans synthetic and biological catalysts, and has the potential to integrate the unique properties of both types of catalysts within a single process.
