POROUS SEMICONDUCTOR AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A filter capable of performing collection of organic materials, bacteria, viruses and other hazardous materials and sterilization/decomposition of collected matter at low cost with extremely high efficiency; and a process f or producing the same. In particular, a porous semiconductor constituted of a semiconductor material capable of light emission is formed inside or on the surface of a porous ceramic or metal as a substrate. Electrodes are fitted thereto to thereby obtain a filter. Fluid is filtered while applying voltage so as to emit ultraviolet radiation. Thus, sterilization/decomposition of hazardous materials, etc. can be performed simultaneously with the filtratio n thereof. |
