Description
技术领域
本发明涉及一种复合氧化物催化剂材料的制备方法，特别是一种无定形铁锌复合氧化物催化剂材料的制备方法，属于环境催化与水污染控制技术领域。
背景技术
多相芬顿反应能够产生强氧化性的活性物种，可以去除水中的难降解有机污染物，并且催化剂可以回收利用，成为近年来国际上广泛采用的一种新型高级氧化水处理技术。纳米零价铁、铁的氧化物和负载型铁氧化物是常用的多相芬顿催化剂，但是固体表面的Fe3+在pH较高时转化为Fe2+的速度要远低于低pH时，因此这些催化剂在中高pH时催化活性较低，往往需要辅助紫外光照来加快反应，这大大的增加了运行成本。在太阳能中紫外光所占比例仅有4%-5%，而可见光可占45%，因此，研发具有可见光响应活性的多相芬顿催化剂受到了越来越多的关注。Sánchez等研究发现二氧化钛在室内光源照射下催化芬顿降解亚甲基蓝的活性比暗态时略有提高(Sánchez等，Applied Catalysis B: Environmental,2013, 142–143: 662–667)。将可见光催化剂与多相芬顿催化剂复合是获得具有可见光芬顿活性催化剂的一种有效方法。例如中国专利文献（申请号201510036208.3）报道了一种α-Fe2O3/石墨烯复合材料的制备方法，该复合材料比表面积大，光芬顿活性明显提高。由于铁是芬顿反应的活性组分，所以催化剂的开发更多的集中在含铁的半导体材料上。例如ZnFe2O4可以在可见光照射条件下产生电子和空穴，光生电子可以还原Fe3+为Fe2+或直接和H2O2反应生成，提高对水中酸性橙II的降解效率（Cai等，Applied Catalysis B:Environmental, 2016, 182: 456–468；Su等，Journal of Hazardous Materials, 2012,211–212: 95–103）。然而目前所研究的可见光芬顿催化剂的目标污染物多为有机染料，而有机污染物的结构是影响催化剂性能的一个重要因素，有机染料的降解往往与其自身光敏化有关，无法准确的评价催化剂的活性。此外所研究的催化剂均为具有良好晶型的可见光催化剂，无定形材料由于其自身电子空穴复合效率高，关于其在可见光芬顿领域的研究未见报道。为此，研究无定形材料对水体中有机污染物的可见光芬顿催化降解有着重要意义，更进一步的，寻找一种可见光芬顿催化剂的制备方法，对实现将水中多种有机污染物的高效去除，其意义也就显得尤为重要。
发明内容
本发明的目的在于提供一种无定形铁锌复合氧化物光芬顿催化剂的制备方法。
本发明的目的是这样实现的。一种无定形铁锌复合氧化物光芬顿催化剂的制备方法，包括以下步骤：
（1）在室温条件下，向硝酸铁、硝酸锌和葡萄糖的混合溶液中滴加氢氧化钠溶液，调节pH大于10,在水热釜中控温100-130℃，加热12-24小时；
（2）反应液经抽滤洗涤，将滤饼60℃干燥，得到无定形铁锌复合氧化物。
本发明中，硝酸铁、硝酸锌和葡萄糖最适宜的摩尔比为2:1:（8-16）。
本发明还给出了该无定形铁锌复合氧化物的应用。具体就是该无定形铁锌复合氧化物作为光芬顿催化剂，在可见光中去除水中有机污染物中的应用。以罗丹明B、亚甲基蓝、安替比林和苯酚为目标污染物来评价该无定形铁锌复合氧化物的催化活性。反应温度为室温，光源是装有λ ≥420 nm滤光片的300 W氙灯，水溶液pH=4.5-7.5，过氧化氢浓度为10mmol/L，催化剂的投加量为0.5 g/L。
本发明取得的有益效果如下：本发明的制备方法无环境污染，工艺简单，成本低廉。所制备的无定形铁锌复合氧化物对罗丹明B、亚甲基蓝、安替比林和苯酚均表现出较好的可见光芬顿活性，并且催化剂适宜pH范围较宽，pH=4.5-7.5时可见光照均能明显提高催化芬顿降解污染物效率，对处理酸性和中性有机废水非常有利。
附图说明
图1是实施例1制备的无定形铁锌复合氧化物对罗丹明B的催化活性测试数据图。
图2是实施例1制备的无定形铁锌复合氧化物在不同pH下对罗丹明B的可见光芬顿催化活性图。
图3是实施例1制备的无定形铁锌复合氧化物对亚甲基蓝、安替比林和苯酚的催化活性测试数据图。
具体实施方式
以下实施例用于说明本发明。
实施例1
(1)在室温条件下，向硝酸铁、硝酸锌和葡萄糖的混合溶液中滴加氢氧化钠溶液，调节pH大于10, 硝酸铁、硝酸锌和葡萄糖的摩尔比为2:1:12，在水热釜中120℃加热12小时；
（2）抽滤洗涤，滤饼60℃干燥，得到无定形铁锌复合氧化物。
将所得样品用XRD（X射线衍射）测定其晶型，没有观察到任何衍射峰的存在，说明该材料为无定形结构。EDS（扫描电镜能谱）和XPS（X射线光电子能谱）分析结果表明，材料体相和表面的铁锌原子比分别为3:1和1.65:1，表面铁以二价铁为主，二价铁与三价铁的原子比为2.1:1。
（3）催化剂活性评价
将得到的无定形铁锌复合氧化物用于按前述实验方法和条件比较了不同反应体系中罗丹明B的降解情况，结果见附图1。可见光/H2O2和催化剂/可见光体系中罗丹明B的降解率仅有10.5%和16.8%，催化剂/H2O2体系中降解率略有提高，达到36.6%。而在催化剂、可见光和H2O2同时存在时，降解率显著提高，达到了95.2%。
图2比较了不同pH时无定形铁锌复合氧化物催化剂的可见光芬顿活性，随着pH值的降低，罗丹明B的降解速率明显加快，pH4.5时30分钟的降解率就达到93.6%，说明该催化剂在中性和酸性条件下均有良好的催化活性。
图3比较了无定形铁锌复合氧化物催化剂作为光芬顿催化剂，对不同有机污染物的可见光芬顿和暗态芬顿活性，在暗态条件下亚甲基蓝、安替比林和苯酚的降解率仅为34.5%、7.6%和31.2%，而在可见光照条件下降解率显著提升到96.2%、84.1%和99%，说明该催化剂对水中不同的有机污染物均有良好的可见光芬顿活性。
