【摘要】 本文以氯化铁、甘油和尿素为反应物,采用一种设备简单、操作便捷的实验合成方法―水热法,制备了α-Fe₂O₃纳米材料,并采用X-ray射线衍射仪（XRD）对所制备产品的晶体结构进行了表征;用扫描电子显微镜（SEM）对所制备α-Fe₂O₃粒子的形貌和大小进行了观察;以甲基橙溶液为目标降解物,以氙灯为实验光源对产物的光催化性能进行研究,研究表明所得产物对于甲基橙有较好的光催化性能,反应80min后降解率可以达到70%。更多还原

【Abstract】 In this study,the alpha Fe₂O₃ nanometer materials have been prepared,using ferric chloride,glycerol and urea as reactant,and a very simple experiment synthesis method,hydrothermal method. The surface morphology and structure of the product have been characterized,using the X- ray diffraction（ XRD）. The size and morphology of the particle have been observed by scanning electron microscope（ SEM）. With methyl orange solution degradation as the target,with experimental light source of xenon lamp,light catalytic performance of the product have been studied,and the light catalytic properties of the alpha Fe₂O₃ nonmaterial prepared have been expounded. Studies have shown that the resulting product for methyl orange has better photocatalytic performance,and degradation rate can reach 70% after 80 min reaction.更多还原
