Photocatalytic ceramic

Abstract

The present invention relates to a method for producing an antibacterial photocatalytic ceramic that comprises: —making available at least one amorphous metal; —making available a biomimetic material or a biomaterial based on calcium phosphate; —functionalizing said biomimetic material or said biomaterial based on calcium phosphate, with said at least one amorphous metal, obtaining a functionalized and oriented composite; —adding said functionalized composite to a ceramic mixture, and/or applying said functionalized composite on a ceramic semi-finished product, where ceramic semi-finished product means the ceramic material before baking; —applying said functionalized composite on a ceramic semi-finished product; —baking at a temperature between 600 and 1400° C., preferably between 900 and 1300° C., for a time that varies from 20 to 500 minutes, obtaining an antibacterial photocatalytic ceramic. The present invention further relates to a photocatalytic ceramic material that comprises a biomimetic material having a nanostructured hierarchical structure with macro and micro cavities, within which at least one photocatalytic material selected from metal oxides and/or sulphides in the crystalline form with a rutile-like structure is included, and tiles, sanitary ware and tableware comprising the same.
