Samsung patents air filter material that traps pollutants
Samsung has been granted a patent for a new type of air purification catalyst. The material combines porous carbon particles with specific chemical compounds and metal oxides to capture unwanted substances from the air.
In the filing’s own words
An organic-inorganic composite catalyst wherein the organic-inorganic composite catalyst includes a porous carbonaceous particle, a first compound; and a metal oxide particle, wherein the first compound and the metal oxide particle are supported on the porous carbonaceous particle, the first compound contains a polar functional group, an anion, or a combination thereof, the metal oxide is represented by the formula M a O b, wherein 0<a≤4, 0<b≤5, and M is a metal of Groups 2 to 16 of the Periodic Table of Elements, or a combination thereof, and the organic-inorganic composite catalyst is configured to remove a second compound from an unpurified air flow including the second compound.
What exactly they claim (claim 1)
1. An organic-inorganic composite catalyst comprising: a porous carbonaceous particle; a first compound; and a metal oxide particle, wherein the first compound and the metal oxide particle are supported on the porous carbonaceous particle, the first compound comprises a polar functional group selected from an amine group, a polymer containing an amine group, an amide group, a polymer containing an amide group, an imide group, a polymer containing an imide group, or a combination thereof, the metal oxide is represented by the formula M a O b, wherein 0<a≤4, 0<b≤5, and M is a metal of Groups 2 to 16 of the Periodic Table of Elements, or a combination thereof, and the organic-inorganic composite catalyst is configured to remove a second compound from an unpurified air flow comprising the second compound.
