AI Technical Summary

Benefits of technology

[0008]The present invention has been made in order to solve the problems described above, and it is therefore desirable to provide a fungicide which is made of a porous carbon material and which has excellent odor eliminating and sterilization effects, a photo catalytic composite material which absorbs a light in a visible light region and shows a decomposition reaction, an adsorbent which adsorbs a metal, and a depurative.

[0013]In each of the fungicide, the photo catalytic composite material, the adsorbent, and the depurative of the embodiment of the present invention, the value of the specific surface area based on the nitrogen BET method is equal to or larger than 10 m2 / g and a volume of a fine pore based on a BJH method and an MP method is equal to or larger than 0.1 cm3 / g. These requirements can be attained by a porous carbon material. In addition, the functional material is adhered to such a porous carbon material, thereby making it possible to increase an amount of functional material adhered per unit weight of the porous carbon material. Also, it is possible to obtain the porous carbon material complex having the high property and the high functionality.

[0014]Also, in the fungicide of the embodiment of the present invention, the high adsorption property and the high sterilization can be obtained because the silver member is adhered to the porous carbon material. Thus, the fungicide can also be utilized as a deodorant product, a deodorizer, an antimicrobial agent or preserving agent. In addition, in the photo catalytic composite material of the embodiment of the present invention, the photo catalytic material is composed of the titanium oxide doped either with the cation or with the anion. Therefore, the photo catalytic composite material of the embodiment of the present invention can effectively absorb the visible light, and thus is given a charge separation property, a visible light absorption property, an ultraviolet ray absorption property, and a catalyst property. Thus, the photo catalytic composite material of the embodiment of the present invention can be applied as a harmful material decomposition agent, and a harmful material remover which can be semi-permanently used due to the photo catalytic effect. In addition, in each of the adsorbent and the depurative of the embodiment of the present invention, the metal (a metal atom or a metal ion) can be effectively adsorbed because the organic material is adhered (supported, adsorbed or bonded) to the porous carbon material.

[0015]Moreover, the porous carbon material of the embodiment of the present invention is regulated in its volume of the fine pore, and has a fine pore in a meso region (in the range of 2 to 50 nm) which cannot be realized in existing activated carbon in addition to the fine pore in a micro region (<2 nm) which the existing activated carbon has. Also, the fungicide of the embodiment of the present invention shows the high adsorption capacity for the molecules as the cause of the aroma due to such a fine pore size. In addition thereto, the funguses are adsorbed by a macro fine pore (>50 nm) having the porous carbon material and dispersed, thereby also suppressing the growth of the funguses. In addition, in the photo catalytic composite material of the embodiment of the present invention, the photo catalytic material can be very effectively adhered to the porous carbon material based on the fine pore size as described above, and thus the decomposition based on the photo catalytic action can be effectively caused. In addition, in each of the photo catalytic composite material, the adsorbent and the depurative of the embodiment of the present invention as the material for the environment depuration, it is expected that the fine pore size as described above effectively act on the adsorption of the harmful materials. At the same time, the photo catalytic material or the organic material can be very effectively adhered to the porous carbon material, and thus the decomposition and detoxification of the harmful materials can be effectively caused. In addition, the diffusion of the harmful materials in the inside of the porous carbon material is promoted, which results in that the decomposition can be more effectively caused, and the depuration of the water, and the depuration of the air can be very effectively carried out.

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.
