Description
技术领域
本发明涉及微纳米结构材料的制备技术领域，特别是一种制备AgFe3(SO4)2(OH)6可见光磁性催化剂的方法。
背景技术
光催化剂是指在光子的激发下能够起到催化作用的各类半导体材料。主要包括二氧化钛(TiO2)、氧化锌(ZnO)、氧化锡(SnO2)、二氧化锆(ZrO2)和硫化镉(CdS)等多种化合物半导体。光催化除污技术具有设备简单、操作条件易控制、非选择性的氧化有机污染物、运行费用低、无二次污染并且催化剂可回收利用等突出优点，在有机废水治理方面有着广阔的应用前景。光催化逐步向更高效利用日光，实用化方向发展，寻找能直接利用太阳光的催化剂是光催化领域的一个重要发展方向。
铁矾是指两种或两种以上金属的硫酸盐所组成的碱式硫酸盐的复盐，主要有：黄钾铁矾、草黄铁矾、黄铵铁矾、银铁矾、黄钠铁矾和铅铁矾六种，它们都是在酸性环境中形成的。铁矾一旦形成，就很稳定，不溶于酸，因此，铁矾的沉淀反应可用于从硫酸盐溶液中除铁。铁矾分子式可写成MFe3(SO4)2(OH)6，M＋为一价阳离子(主要包括Na＋、K＋、NH4 ＋、Ag＋、Rb＋和0.5Pb2＋等)。例如，钠铁矾[Na2Fe6(SO4)4(OH)12]、铅铁矾[Pb0.5Fe3(SO4)2(OH)6]和银铁矾[Ag2Fe6(OH)12(SO4)4]都是已知的铁矾。通常，铁矾可采用化学法和生物化学法来制备。铁矾本身一般具有解毒杀虫、敛疮等的功效，在医学领域应用广泛。同时，煅烧质量纯的铁矾可得到用于研磨的各类材料。

具体实施方式
下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
一种制备AgFe3(SO4)2(OH)6可见光磁性催化剂的方法，包括以下步骤：
（1）将FeSO4.7H2O加入到去离子水中配成硫酸亚铁水溶液；
（2）称取AgNO3加入到步骤（1）中所述的硫酸亚铁水溶液中，在常温常压下，通过快速还原反应得到Ag-Fe2(SO4)3-H2O反应体系；
（3）再向步骤（2）中制得的Ag-Fe2(SO4)3-H2O反应体系中加入FeSO4.7H2O，在空气中快速搅拌反应多个小时后即得AgFe3(SO4)2(OH)6粉体。
AgNO3、FeSO4.7H2O和Fe2(SO4)3以及空气中的O2之间具有相互配合、缺一不可的关系。
步骤（1）中所述硫酸亚铁水溶液的浓度为0.01-0.4mol/L。
步骤（2）中所述AgNO3的质量为0.10-0.5g。
步骤（3）中添加的FeSO4.7H2O的质量为1-3g。
步骤（3）中在空气中快速搅拌的速率为100-200转/分钟。
步骤（3）中在空气中快速搅拌反应时间超过12h。
本发明的实施例1：
取0.2g AgNO3加入到100mL浓度为0.2mol/L的FeSO4.7H2O水溶液中，反应30分钟后，再加入0.3g FeSO4.7H2O，超声溶液和反应若干时间后即可获得目标产物。首先，利用X-衍射手段对产物结构进行分析后表明，产物的XRD谱图与块体AgFe3(SO4)2(OH)6的标准XRD谱图(PDF#41-1398)对应完好(见图1)，说明实验得到的粉体为菱方结构的AgFe3(SO4)2(OH)6。接着，采用SEM手段对产物的形态和化学组成进行了分析，其结果如图2所示。由图2a可以看出，产物的形态多为圆片状聚集体，尺寸较大。对单个圆片进行面扫描和线扫描能谱分析结果表明，单个圆片主要是由Ag、Fe、S和O四种元素构成(见图2b)。线扫描结果初步表明，Ag:Fe:S三者比例约为0.83:4.81:2.8，接近于1:3:2，也可以说明产物组成为AgFe3(SO4)2(OH)6(见图2c)。基于上述部分实验结果，可以认为AgFe3(SO4)2(OH)6的形成过程如下：首先，Ag+被Fe2+快速还原成Ag，之后Ag又被Fe3+缓慢氧化成Ag+，最后，在含有Ag+、Fe3+和高浓度的SO4 2-的酸性环境中形成了AgFe3(SO4)2(OH)6。反应过程可如下两个式子表示。
利用公式可以来计算AgFe3(SO4)2(OH)6光带隙，其中h为普朗克常量，是 光的频率，Eg为光带隙能量值，α为吸光度，n对于间接带隙型半导体取0.5， 对于直接带隙型半导体2。以(αhν)n为纵坐标，hν为横坐标作图，对其中线性 区段进行拟合，得到一个线性方程，它在x轴截距即是带隙能量的大小。
首先，测得了黄色AgFe3(SO4)2(OH)6粉体的紫外-可见吸收光谱图(见3a)， 然后，利用上述方法得到(αhν)0.5-hν曲线(见3b)，可以估算出AgFe3(SO4)2(OH)6粉体的带隙约为1.9eV。最后，将一定量粉体分散于水中，外加一定强度的磁 场，约10分钟后，分散的产物将完全富集到瓶壁上，说明实验产物具有良好 的磁性能。
以上依据图式所示的实施例详细说明了本发明的构造、特征及作用效果，以上所述仅为本发明的较佳实施例，但本发明不以图面所示限定实施范围，凡是依照本发明的构想所作的改变，或修改为等同变化的等效实施例，仍未超出说明书与图示所涵盖的精神时，均应在本发明的保护范围内。
