Abstract
Provided are materials and processes for removing nitrogen dioxide gas from a sample by contacting the sample with a filtration media that includes a MOF, optionally an amine containing MOF. The resulting filtration media has the ability to sequester nitrogen dioxide with little conversion to nitric oxide, is stable, and highly functional so as to be useful in protective equipment or other filtration systems.
Claims24
A process for removing nitrogen dioxide from a gaseous sample, comprising:
- moving a gaseous sample including nitrogen dioxide through a filter comprising a filtration media, said filtration media comprising a metal organic framework (MOF), said filtration media suitable to decrease the nitrogen dioxide level in the gaseous sample.
A filtration media capable of reducing nitrogen dioxide concentration in a gas sample, comprising:
- a metal organic framework (MOF), wherein said MOF includes a functional group capable of reacting with nitrogen dioxide.
