    • 본 발명은 마이크로파에 의한 무기소재 박막의 제조방법에 관한 것으로, 더욱 상세하게는 기판(Substrate), 기판과 무기막을 접착하는 접착층, 그리고 무기 결정막이 차례로 적층되어 있는 무기소재 박막을 제조하는데 있어, 상기한 접착층에는 사용되는 무기막 소재보다 상대적으로 유전도가 높은 나노크기의 금속산화물 또는 금속 실리케이트 산화물을 박막 코팅하여 무기접착층을 형성한 후에, 무기막을 형성하기 위한 무기결정 전구용액 또는 무기결정 용액에 담그어 마이크로파를 조사하므로써 상대적으로 유전도가 높은 무기접착층에 무기결정이 선택적으로 흡수되어 규칙적인 배향으로 그리고 강력한 결합력으로 나노조립되도록 하는 마이크로파에 의한 무기소재 박막의 제조방법에 관한 것이다. 수열방법을 비롯한 무기물을 이용한 종래 방법에 의하면 무기결정 박막의 나노조립이 용이하지 않고, 또 무기 결정이 막으로부터 쉽게 분리되는 단점이 있으나, 본 발명의 제조방법에 의하면 무기결정이 무기접착층과 강력한 결합력으로 나노조립되는 우수성이 있다.

    • The present invention relates to a novel titania photocatalyst and its manufacturing method. More specifically, the present invention is to provide the quantum-sized novel titania photocatalyst prepared the steps comprising: (a) titanium tetraisopropoxide is encapsulated in zeolite support by adding citric acid to isopropyl alcohol; (b) ethylene glycol is dissolved herein to obtain a uniformly dispersed mixture solution; and (c) it is encapsulated in zeolite cavities. And thus, titania photocatalyst of the present invention has some advantages in that (a) it provides greatly increased surface area and photocatalytic activity due to the smaller granule than the commercial titania powder; (b) it is uniformly dispersed to quantum size zeolite cavities rather than forming large clusters caused by the aggregation of the conventional titania hyperfine powder; and (c) since the quantum efficiency of titania powder in the UV region is maximized thereby, it effectively and promptly removes the hazardous gas like ammonia and sulfide in the atmosphere and organic material in water waste through photo-oxidation reaction.
