Benefits of technology

The present invention provides a solution to problems such as odor and sterilization issues. The invention includes a fungicide made of a porous carbon material with excellent odor eliminating and sterilization effects, a photo catalytic composite material that absorbs light and shows decomposition reaction, an adsorbent that adsorbs metals, and a depurative. The functional materials are adhered to the porous carbon material, making it possible to increase the amount of functional material per unit weight of the carbon material. The fungicide can also be used as a deodorant, deodorizer, antimicrobial agent, or preserving agent. The photo catalytic composite material can effectively absorb visible light and has a high adsorption capacity for molecules that cause odor. The fine pore size in the porous carbon material also promotes the diffusion of harmful materials, resulting in more effective decomposition and detoxification.

Problems solved by technology

However, it is difficult to say that the Ag containing zeolite described above has the sufficient property in terms of the odor eliminating and the sterilization.
In addition, the functional material, having the light absorption property, in which a titanium oxide (TiO2) is supported by the porous material involves such a problem that the functional material concerned hardly absorbs a light in a visible light region and thus does not show the high decomposition reaction.
Or, the porous carbon material as the case may involve such a problem that the porous carbon material concerned hardly adsorbs the metal.
