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先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 antibac-terial mechanism of the ceramic have been investigated. Heat treated at 1323K, the modified TiO2 powder added 37.2% Zr3 (PO4)4 and 11.50%SiO2 showed a well photocatalysis activity,antibacterial ratio of the photocatalysis antibacterial ceramic to coliform have reached 98 %.
