BIFUNCTIONAL ACTIVE SITES FOR ADSORPTION OF NOX

摘要

Immobilized nitronyl nitroxide active sites on the surface of a porous inorganic oxide support act as efficient and rapid oxidants for NO, reacting with > 99% of the NO under flow conditions through a packed bed; and, in a parallel configuration with nitroxyl radical active sites, act to remove > 99 % of both NO and NO2 from a gas mixture, with > 95% of the active sites participating in NOx trapping.
