The adsorption, storage and release of nitric oxide using ion exchanged zeolites
Zeolites exchanged with transition metal cations Co2+, Mn2+, Zn2+ and Cu2+ are capable of storing and delivering a large quantity of nitric oxide in a range of 1.2-2.7mmolg-1. The metal ion exchange impacts the pore volumes of zeolite FAU more significantly than LTA. The storage of NO mainly involves coordination of NO to metal cation sites. By exposing zeolites to a moisture atmosphere, the stored nitric oxide can be released. The NO release takes more than 2 hours for the NO concentration decreasing below ~5ppb in outlet gas. Its release rate can be controlled by tailoring zeolite frameworks and optimising release conditions.
