本次实验是以MnCl2.4H2O和FeCl3.6H2O作为原料,以氢氧化钠为沉淀剂,采用共沉淀法制备出前驱体MnO(OH)和FeO(OH),然后快速脱水制得MnFe2O4,通过在不同温度焙烧得到最佳催化产物.实验原料的Fe/Mn摩尔比（x）始终为2：1,实验主要是通过控制反应温度以及焙烧温度制得最佳催化产物.并以H2O2为催化剂比较它对亚甲基兰氧化分解的催化活性.结果表明制备的催化剂的催化效率较高,催化分解亚甲基兰,脱色率能达到93%以上,产物的表征手段主要有粉末X射线衍射（XRD）和透射电镜（TEM）

This experiment is MnCl2.4H2O and FeCl3.6H2O as raw materials to sodium hydroxide to sedimentation agents, the introduction of the rule of law for a total precipitation of valuable body MnO (OH) and FeO (OH), and then rapid dehydration of a MnFe2O4 through different temperature roasting in the best catalyst product. Experimental raw materials than Fe/Mn Moore (x) for 2:1 always, the experiment primarily through temperature control system in response to temperature and roast the best catalyst product. H2O2 as a catalyst and to compare its Asian a Kieran oxidation catalytic decomposition of reactive. Prepared catalyst showed higher catalytic efficiency, the catalytic decomposition Asian a Kieran, detreated rate can reach 93% or more, the expression means a product mainly powder X-ray diffraction (XRD) and Toushedianjing (Tem)
