Abstract

A carbonized material, a device for removing ozone, and a method for removing ozone are provided. The carbonized material has at least a carbonyl-containing group, alkylol group, and carbon having sp 2 hybrid orbital. In particular, the at least one carbonyl-containing group has a carbon content from 10 atom % to 30 atom %, based on the total carbon atoms of the at least one carbonyl-containing group, the at least one alkylol group, and the at least one carbon having sp 2 hybrid orbital.

First claim

What is claimed is:

1. A carbonized material, comprising: at least one carbonyl-containing group; at least one alkylol group; and at least one carbon having sp 2 hybrid orbital, wherein the at least one carbonyl-containing group has a carbon content from 10 atom % to 30 atom %, based on the total carbon atoms of the at least one carbonyl-containing group, the at least one alkylol group, and the at least one carbon having sp 2 hybrid orbital.

2. The carbonized material as claimed in claim 1 , wherein the carbonyl-containing group is selected from the group consisting of carbonyl group, carbonyloxy group and oxycarbonyl group.

3. The carbonized material as claimed in claim 1 , wherein the at least one carbonyl-containing group has a carbon content from 10 atom % to 25 atom %, based on the total carbon atoms of the at least one carbonyl-containing group, the at least one alkylol group, and the at least one carbon having sp 2 hybrid orbital.

4. The carbonized material as claimed in claim 1 , wherein 1.0 g of the carbonized material is capable of decomposing 0.8 g-2.0 g of ozone with a relative humidity of 95% at 25° C.

5. A device for removing ozone, comprising:
a chamber; and
the carbonized material as claimed in claim 1 , disposed within the chamber.

6. The device for removing ozone as claimed in claim 5 , further comprising:
an inlet for introducing a gas into the chamber; and
an outlet for exhausting the gas passing through the carbonized material from the chamber.

7. The device for removing ozone as claimed in claim 6 , further comprising:
a humidifier connected to the chamber in order to maintain a specific relative humidity in the chamber.

8. A method for removing ozone, comprising:
providing a gas, wherein the gas has an ozone concentration that is higher than or equal to 0.1 ppm; and
forcing the gas to pass through the carbonized material as claimed in claim 1 , such that the ozone of the gas reacts with the carbonized material.

9. The method as claimed in claim 8 , wherein the ozone is converted into carbon dioxide and water after reacting with the carbonized material.

10. The method as claimed in claim 8 , wherein the ozone of the gas reacts with the carbonized material with a relative humidity from 10% to 99%.
