图2为介孔复合材料Fe3O4-Co3O4的氮气吸附脱附及孔径分布测试图。
图3为对比试验与介孔复合材料Fe3O4-Co3O4对气态污染物降解效果对比图。
具体实施方式
实施例1
(一)介孔复合材料Fe3O4-Co3O4的制备
1)将2.57g六水合硝酸钴和2.02g九水合硝酸铁分别溶解于50mL的水溶液中,分别得含有铁的溶液和含有钴的溶液。
2)将步骤1)所得含有铁的溶液和含有钴的溶液混合均匀,调节F127的水溶液的浓度为0.06g/mL,倒入15mL F127的水溶液,充分搅拌后将所得样品置于干燥箱中,于100℃干燥10h。
3)将干燥后的样品在马弗炉中,于空气条件下,升温速度为5℃/min,400℃煅烧6h,将煅烧后的样品冷却到室温后进行研磨,得到介孔复合材料Fe3O4-Co3O4。
(二)检测
图1为Co3O4、Fe3O4和实施例1制备的介孔复合材料Fe3O4-Co3O4的XRD测试图,由图1可见,本发明制备的介孔复合材料Fe3O4-Co3O4在30.10°、31.27°、35.45°、36.85°、43.09°和44.81°有六个衍射峰,为Fe3O4-Co3O4的特征峰,证明制备的样品为Fe3O4-Co3O4。
图2为实施例1制备的介孔复合材料Fe3O4-Co3O4的氮气吸附脱附及孔径分布测试图,由图2可见,本发明制备的介孔复合材料Fe3O4-Co3O4符合IV型滞回线的特征,为介孔材料,且比表面积为44.408m2g-1。
实施例2介孔复合材料Fe3O4-Co3O4作为催化剂在降解气态异丙醇中的应用
方法:取0.1克实施例1制备的介孔复合材料Fe3O4-Co3O4放入可加热的实验装置中,并向实验装置中注入5μL液体异丙醇,待异丙醇充分气化后,对实验装置中异丙醇气体浓度进行检测。
对比试验:直接在可加热的实验装置中注入5μL液体异丙醇,待异丙醇充分气化后,对实验装置中异丙醇气体浓度进行检测。
随着温度的增加,测定实验装置中异丙醇气体的降解率。由图3所示,介孔复合材料Fe3O4-Co3O4对异丙醇的降解率逐渐增加,当温度为250℃时,实验装置中装有实施例1制备的介孔复合材料Fe3O4-Co3O4的异丙醇降解率为85%。实验装置中未加入介孔复合材料Fe3O4-Co3O4的异丙醇降解率为10.2%。可见,本发明制备的介孔复合材料Fe3O4-Co3O4能够降解异丙醇,并且能够在一定温度范围内高效地降解异丙醇。当温度为250℃时异丙醇降解量约是对比实验的10倍,本发明所制备的介孔复合材料能够在一定的温度范围内高效、方便的降解异丙醇。
