Visible light excited composite photocatalytic antibacterial ceramic and preparation method thereof
The invention relates to visible-light-excited composite photocatalytic antibacterial ceramic and a preparation method thereof. The visible-light-excited composite photocatalytic antibacterial ceramiccan be applied to sterilization of refrigerators and air conditioners, sewage treatment, indoor and outdoor air purification and the like. The visible light excited composite photocatalytic materialis a compound of copper nitrate, silver nitrate and titanium dioxide. The prepared photocatalytic material is loaded on cordierite honeycomb ceramic and has a relatively good killing effect on escherichia coli and staphylococcus aureus under a visible light condition. The method comprises: a catalytic material preparation process, a catalytic material slurry preparation process and a catalytic material coating process. The photocatalytic antibacterial ceramic coating prepared by the method is uniform in dispersion and high in catalyst activity. Most importantly, modular assembly can be achieved, large-scale industrial production is easy, and the device can be applied to sterilization and antibiosis of household appliances such as refrigerators and air conditioners.
本发明涉及一种可见光激发复合光催化抗菌陶瓷及其制备方法，可应用于冰箱、空调杀菌，污水处理、室内外空气净化等。本发明可见光激发复合光催化材料是硝酸铜、硝酸银与二氧化钛的复合物。将制得的光催化材料负载在堇青石蜂窝陶瓷上，在可见光条件下对大肠杆菌和金黄色葡萄球菌有较好的杀灭作用。该方法包括：催化材料制备过程，催化材料浆料制备过程及催化材料涂覆过程。本发明制备的光催化抗菌陶瓷涂层分散均匀，催化剂活性强。最主要特点是可以实现模块化组装，易于大规模工业化生产，可应用于冰箱、空调等家电杀菌、抗菌。
