Document Type and Number:
Japanese Patent JP5839722
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high-efficiency photocatalyst without using existing advanced techniques or expensive materials.SOLUTION: In the provided method for manufacturing a metal ion-mixed, calcium carbonate-containing photocatalytic composite composition, a matrix having a photocatalytic function and a calcium carbonate component including a naturally derived calcium carbonate such as fossil coral, etc. are mixed, whereas the resulting mixture is treated, in the presence of metal ions, with a treatment liquid including phosphoric acid and calcium so as to become coated with porous calcium phosphate.
