[0012] Referring to the drawings, the catalyst fresh-keeping block includes an activated carbon adsorbent matrix 3, and a non-woven packaging bag 1 with an antibacterial agent added on the surface of the matrix. The bottom surface of the base is provided with a fiber mesh layer 2 to prevent the base from breaking. When the matrix is multiple layers, multiple layers of fiber nets can be arranged alternately.
[0013] The preparation method of the fresh-keeping block matrix is: first put powdered palladium and activated carbon in a closed container and stir, so that the powdered palladium fully adheres to the surface of the activated carbon to make palladium impregnated carbon. Then the copper oxide, manganese dioxide, polyethylene, silicon dioxide and palladium impregnated carbon are evenly mixed and filled into the mold, then heated and sintered, and taken out after cooling to become the product. The molded product can be used after being cut into blocks of different sizes or sh...
