Abstract
A substrate including a conversion catalyst for removing a volatile organic compound from ambient air. The substrate includes at least one porous wall. The conversion catalyst is within the pores of the at least one substrate porous wall.
Claims29
An article comprising:
- a honeycomb substrate comprising a plurality of porous partition walls defining a plurality of adjacent flow-through channels,
- the porous partition walls comprise a surface area from about 1500 m2/m3 to about 3000 m2/m3 and a porosity from about 45% to about 70%,
- a conversion catalyst within the pores of the porous partition walls of the honeycomb substrate, and
- the conversion catalyst removes a volatile organic compound from a target gas.

A formaldehyde filtration article comprising:
- a substrate comprising a plurality of porous partition walls defining a plurality of flow-through channels, the porous partition walls comprise a surface area,
- a formaldehyde conversion catalyst loaded within the pores of the porous partition walls of the substrate,
- the porous partition walls comprise a porosity when the catalyst is loaded within the pores of the porous partition walls, and
- wherein a ratio of the porosity of the porous partition walls when the catalyst is loaded within the pores of the porous partition walls to the surface area of the porous partition walls is greater than about 0.017.
