Zusammenfassung:The present invention relates to a high efficiency photocatalyst coating composition, and to a manufacturing method thereof and, more specifically, to a high efficiency photocatalyst coating composition, which firstly selects a TiO_2 photocatalyst with an anatase type of 98% or more, selects modified polysiloxane having excellent performance as a TiO_2 photocatalyst binder, wherein the modified polysiloxane is a material capable of acting as an organic-inorganic hybrid binder of the photocatalyst, specially limits a solid content ratio into 7% or less based on an aqueous alcohol solution, and has excellent coating properties and light resistance and high purification performance of contaminants, and to a manufacturing method thereof. 본 발명은 효율이 높은 광촉매 코팅용 조성물 및 그 제조방법에 관한 것으로 더욱 상세하게는, 본 발명은 우선 아나타제형이 98% 이상인 TiO광촉매를 선택하고, 상기 광촉매의 유무기 하이브리드 바인더 역할을 할 수 있는 물질이며 TiO광촉매용 바인더로서 우수한 성능을 가지는 변성 폴리실록산을 선택하여, 특별히 알코올 수용액을 기반으로 고형분 비율을 7% 이하로 제한하여, 코팅성 및 내광성이 우수하고 높은 오염물의 정화성능을 가진 효율이 높은 광촉매 코팅용 조성물 및 그 제조방법을 제공하는 것을 특징으로 한다.
