PHOTO-CATALYTIC FILTER FOR DEGRADING MIXED GAS AND MANUFACTURING METHOD THEREOF

The present disclosure relates to a photo-catalytic filter, the surface of which has enhanced adsorption performance so that mixed gases including a gas that reacts later in a competitive reaction can be degraded from the initial stage of a photo-catalytic reaction, and to a manufacturing method thereof. The method includes: dispersing carbon dioxide (TiO2) nano powder as a photo-catalyst and one or more metal compounds in water to prepare a photo-catalytic dispersion; coating a support with the photo-catalytic dispersion; drying the coated support; and sintering the dried support. The photo-catalytic filter includes a support, and a photo-catalyst and one or more metal compounds, which are coated on the support. 本发明涉及一种用于降解混合气体的光催化过滤器及其制造方法，尤其涉及一种其表面具有加强的吸收性能以便包含在竞争反应中较迟反应的气体的混合气体能够从光催化反应的初始阶段被降解的光催化过滤器及其制造方法。该方法包括如下步骤：将作为光催化剂的二氧化钛(TiO2)纳米粉末和一种或多种金属复合物分散在水中以制备光催化分散体；用该光催化分散体涂覆支撑体；干燥对经涂覆的支撑体；以及烧结经干燥的支撑体。该光催化过滤器包括支撑体、以及涂覆在支撑体上的光催化剂和一种或多种金属复合物。
