PHOTOLYSIS CATALYST COMPRISING MATERIALS WITH DIFFERENT BAND GAP ENERGY AND METHOD FOR PREPARING THE SAME

摘要

A photolysis catalyst and a manufacturing method thereof are provided to remove an aromatic cyclic compound effectively by increasing oxidizing potential, and to offer long lifetime of the catalyst. A photolysis catalyst comprises a support, a photocatalyst layer fixed on the supporter, a catalyst having band gap energy less than 3.0 eV, and a titandioxide catalyst. The photocatalyst layer includes a first catalyst layer containing the catalyst having the band gap energy, and a second catalyst layer containing the titandioxide catalyst, and fixed on the first catalyst layer.
