La0.7Sr0.3MnO3-δ/TiO2复合氧化物制备及其协同光催化作用
Abstract:
利用酵母-水解热解法制备了磁性复合氧化物光催化剂La0.7Sr0.3MnO3-δ/TiO2，此复合物能充分利用太阳光，在太阳光下能对有机废水如甲基橙废水及生化处理后的焦化废水进行协同光催化作用，对经生化处理后焦化废水光催化降解的协同指数在不同波长的光照下，指数在1.0-1.6之间；对模拟甲基橙废水，太阳光下40分钟后的协同催化指数为1.79。所以，本发明合成的La0.7Sr0.3MnO3-δ/TiO2是一个具有磁性和太阳光活性的多功能光催化剂。
Abstract(English):

The invention discloses a method for preparing a magnetic composite oxide photocatalyst La0.7Sr0.3MnO3-delta/TiO2 through a yeast-hydrolysis pyrolysis method. The composite oxide fully uses sunlight, can be used for synergetic photocatalysis of organic wastewater such as methyl orange wastewater and biochemical treatment coking wastewater under sunlight, has a synergic index of photocatalytic degradation of biochemical treatment coking wastewater in 1.0-1.6 under irradiation of lights with different wavelengths and has a simulated methyl orange wastewater synergic catalysis index of 1.79 under sunlight irradiation for 40min. The La0.7Sr0.3MnO3-delta/TiO2 is a multifunctional photocatalyst having magnetism and sunlight activity.
