Title Honeycomb structure and manufacturing method thereof, and air cleaner and water purifier containing the honeycomb structure
Abstract (US7883563)
A composite honeycomb structure in which the honeycomb structure is highly functionalized and adapted to have catalytic function, considering pressure loss is provided.
A honeycomb structure having average pore diameter of 5 to 200 μm and specific surface area of 100 to 1500 m2/g is provided.
Further, a translucent honeycomb structure and a photocatalyst-carrying translucent honeycomb structure having a photocatalyst carried on a surface of the translucent honeycomb structure and/or contained in the translucent honeycomb structure are provided.
Further, an air cleaner and a water purifier using the honeycomb structure and the photocatalyst-carrying translucent honeycomb structure are provided.
Scope of claims [claim1]
1. A honeycomb structure having average pore diameter of 5 to 200 mu m and specific surface area of 700 to 1000 m2/g, wherein said honeycomb structure is made of silica gel.
[claim2]
2. The honeycomb structure according to claim 1, which is porous.
[claim3]
3. A composite honeycomb structure having metal fine particles carried on a surface of the honeycomb structure according to claim 1 and/or having the metal fine particles contained in the honeycomb structure.
[claim4]
4. The composite honeycomb structure according to claim 3, wherein noble metal is used as said metal fine particles.
[claim5]
5. The composite honeycomb structure according to claim 3, whereinplatinum and/or silver is used as said metal fine particles.
[claim6]
6. An air cleaner using the composite honeycomb structure according to claim 3 as a filter.
[claim7]
7. A water purifier using the composite honeycomb structure according to claim 3 as a water purifying filter.
[claim8]
8. A translucent honeycomb structure having average pore diameter of 5 to 200 mu m and specific surface area of 700 to 1000 m2/g , wherein said translucent honeycomb structure is made of silica gel.
[claim9]
9. A photocatalyst-carrying translucent honeycomb structure having a photocatalyst carried on a surface of the translucent honeycomb structure according to claim 8 and/or having the photocatalyst contained in the translucent honeycomb structure.
[claim10]
10. An air cleaner using the photocatalyst-carrying translucent composite honeycomb structure according to claim 9 as a filter.
[claim11]
11. A water purifier using the photocatalyst-carrying translucent composite honeycomb structure according to claim 9 as a water purifying filter.
