| 摘 要： | 本研究制备了表面镀有光催化剂薄膜的光催化陶瓷,并利用 XRD、色谱、原位红外光谱和分光光度计等研究了其光催化降解油酸、乙烯、SO2、NOx和灭菌的特性.结果表明,通过控制制备条件得到的光催化陶瓷具有较强的降解有机污染物、去除无机有害气体和灭菌等功能.光催化功能陶瓷对乙烯、油酸、SO2和NOx的降解率达到95%～100%.

| Abstract: | Photocatalytic ceramic was prepared by coating photocatalytic membrane on ceramic matrix. The photocatalytic behavior of the TiO2 coated ceramic for degradation of oleic acid, ethylene, SO2, NOx and sterilization was studied by using XRD, chromatogram, in-situ IR and spectrophotometer. The results showed that the photocatalytic ceramic prepared by special conditions have the function of environmental conservation such as the photodegradating organic contaminants, removing inorganic baleful gas and killing bacteria. Degradation ratio of ethylene, oleic acid, SO2 and NOx reached 95%-100% respectively for the photocatalytic functional ceramic. |
