摘要
制备了SiO2-Zr3(PO4)4改性的TiO2粉体,将其添加到陶瓷釉料中,研制出了TiO2光催化抗菌陶瓷,分别就改性TiO2粉体的光催化活性和TiO2光催化抗菌陶瓷的光催化抗菌机理进行了研究。研究表明,37.2%Zr3(PO4)4和11.5%SiO2改性的TiO2粉体经1323K处理后,仍具有较好的光催化活性,将其添加到陶瓷釉料中制备出的TiO2光催化抗菌陶瓷对大肠杆菌的抑菌率达98%。
TiO2 photocatalysis antibacterial ceramic was prepared by added TiO2 powder modified by SiO2-Zr3 （PO4）4 in ceramic glaze. The photocatalysis mechanism of modified TiO2 powder and the photocatalysis antibacterial mechanism of the ceramic have been investigated. Heat treated at 1323K,the modified TiO2 powder added 37.2% Zr3 （PO4）4 and 11.5% SiO2 showed a well photocatalysis activity, antibacterial ratio of the photocatalysis antibacterial ceramic to coliform have reached 98%.
