Photocatalytic ceramic
The invention relates to a method for producing antibacterial photocatalytic ceramics, comprising:-preparing at least one amorphous metal available; -preparation of available biomimetic or biomaterials based on calcium phosphate; -functionalizing said biomimetic material or said biomaterial based on calcium phosphate with said at least one amorphous metal, thereby obtaining 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 representing the ceramic material prior to baking; applying the functionalized composite material to a ceramic semi-finished product; -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, thereby obtaining the antibacterial photocatalytic ceramic. The invention also relates to a photocatalytic ceramic material comprising a biomimetic material having a nanostructured hierarchical structure having macroscopic and microscopic cavities, within which at least one photocatalytic material is contained, and a tile, sanitary ware and dishware comprising the photocatalytic ceramic material, the photocatalytic material is selected from metal oxides and/or sulfides in a crystalline form with a rutile-like structure.
本发明涉及用于生产抗菌光催化陶瓷的方法，其包括：‑制备可用的至少一种非晶态金属；‑制备可用的基于钙磷酸盐的仿生材料或生物材料；‑用所述至少一种非晶态金属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烤之前的陶瓷材料；‑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℃之间的温度下烘烤持续从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和包含光催化陶瓷材料的砖瓦、卫生器具和餐具，该光催化陶瓷材料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和微观腔，在所述腔内包括至少一种光催化材料，所述光催化材料选自处于具有类金红石结构的晶态形式的金属氧化物和/或硫化物。
