(57) Abstract: A manufacturing process of a photocatalyst for decomposing and removing pollutants in water by a photocatalyst is simplified and the retention of catalyst particles is stabilized. SOLUTION: Photocatalyst powder 1b for oxidatively decomposing pollutants And magnetic powder 1c for magnetically separating and recovering the photocatalyst from water, and fluororesin powder 1a as a binder are mixed and stirred, and this is rolled and then cut into strips to form a photocatalyst. 1 is formed. In addition to being easy to manufacture, the fluororesin is stable against the oxidation action of the photocatalyst, and the catalyst particles 1b do not separate or flow out. |
