Abstract
The present invention provides for a device for reducing a volatile organic compound (VOC) content of a gas comprising a manganese oxide (MnOx) catalyst. The manganese oxide (MnOx) catalyst is capable of catalyzing formaldehyde at room temperature, with complete conversion, to CO2 and water vapor. The manganese oxide (MnOx) catalyst itself is not consumed by the reaction of formaldehyde into CO2 and water vapor. The present invention also provides for a device for reducing or removing a particle, a VOC and/or ozone from a gas comprising an activated carbon filter (ACF) on a media that is capable of being periodically regenerated.

10. A method for reducing formaldehyde content of a gas, comprising:
at room temperature, contacting the formaldehyde-containing gas with a manganese-containing catalyst comprising majority non-stoichiometric manganese oxide-hydroxide particles having a Brunner Emmet and Teller (BET) surface area of at least 100 m2 g−
1, thereby obtaining a gas having a reduced formaldehyde content as compared to the gas prior to contact with the manganese-containing catalyst.- View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
