The present invention relates to a photocatalytic ceramic, in particular to a method for producing an antibacterial photocatalytic ceramic, comprising: preparing available amorphous Ti; preparing an available calcium phosphate-based biomimetic material or biological material; functionalizing the biomimetic material or the biomaterial based on calcium phosphate with the amorphous Ti to obtain a functionalized and oriented composite material; adding the functionalized composite material to a ceramic mixture, and/or applying the functionalized composite material to a ceramic semi-finished product, the ceramic semi-finished product referring to the ceramic material before baking; applying the functionalized composite material to the ceramic semi-finished product; obtaining the antibacterial photocatalytic ceramic by baking at a temperature between 600 and 1400 DEG C, preferably between 900 and 1300 DEG C, for a time varying from 20 to 500 minutes. The present invention also relates to a photocatalytic ceramic material comprising a biomimetic material having a nanostructured hierarchical structure having a macroscopic or microcosmic cavity within which TiO2 is included in rutile crystalline form, and to tiles, sanitary ware and tableware comprising a photocatalytic ceramic material.
本发明涉及光催化陶瓷，具体地涉及用于生产抗菌光催化陶瓷的方法，其包括：‑制备可用的非晶态Ti；‑制备可用的基于钙磷酸盐的仿生材料或生物材料；‑用所述非晶态Ti将基于钙磷酸盐的所述仿生材料或所述生物材料功能化，从而获得功能化且取向的复合材料；‑将所述功能化的复合材料添加至陶瓷混合物，和/或在陶瓷半成品上施加所述功能化的复合材料，其中陶瓷半成品意指烘焙之前的陶瓷材料；‑在陶瓷半成品上施加所述功能化的复合材料；‑在600和1400℃之间、优选在900和1300℃之间的温度下烘焙持续从20至500分钟变化的时间，从而获得抗菌光催化陶瓷。本发明还涉及光催化陶瓷材料，其包含具有纳米结构化的分级结构的仿生材料，所述纳米结构化的分级结构有宏观腔或微观腔，在所述腔内以金红石晶态形式包括TiO2，并且涉及包含光催化陶瓷材料的砖瓦、卫生洁具和餐具。
