Adsorbent, porous filter, air cleaning device, method of cleaning air, and method of manufacturing porous filter
An adsorbent including a porous member having holes and a nanostructure formed on at least a portion of a surface of the porous member, and an air cleaning device including the adsorbent. A porous filter including a porous member having holes and a nanostructure formed on at least a portion of a surface of the porous member, and an air cleaning device including the porous filter. A method of cleaning air for decomposing a hazardous substance using the porous filter and a decomposition gas including a superheated water vapor. A method of manufacturing a porous filter including the steps of growing a nanostructure on at least a portion of a surface of a porous member having holes, allowing a catalyst particle to be contained in a dispersion gas including a superheated water vapor, and spraying the dispersion gas on a surface of the nanostructure to attach the catalyst particle thereto.
1. A porous filter, comprising:
a porous member having a plurality of holes; and
a nanostructure formed on an interior hole surface of said porous member.
2. The porous filter according to claim 1 , wherein said nanostructure is formed with carbon.
3. The porous filter according to claim 1 , wherein said porous member is resistant to heat of at least 200° C.
4. An air cleaning device comprising the porous filter according to claim 1 .
5. A method of cleaning air, comprising the step of
decomposing a hazardous substance using a porous filter and a decomposition gas including a superheated water vapor,
wherein the porous filter has a porous member with a plurality of holes, and
a nanostructure formed on at least a portion of a surface of said porous member.
6. The method of cleaning air according to claim 5 , wherein said decomposition gas contains a decomposition acceleration gas.
7. A porous filter, comprising:
a porous member having a plurality of holes; and
a nanostructure formed on an interior hole surface of said porous member,
wherein the nanostructure filters a volume of air passing through the holes.
