Description
技术领域
本发明涉及纳米胶囊制备技术领域，具体是涉及一种β-FeOOH纳米胶囊的制备方法。
背景技术
羟基氧化铁是(FeOOH)通常存在于河床和矿山等地方，是自然界中一种重要的多层状结构化合物，可用作催化剂、颜料、吸附剂和磁性材料等。FeOOH常见有α-，β-，γ-和δ-FeOOH四种同素异构体。研究表明，当条件符合时，这几种羟基氧化铁彼此之间可以发生相互转变。当前，有关这四种类型的各种形态的FeOOH纳米材料的制备及其应用研究很多。但未见有关FeOOH纳米胶囊的制备和应用报告。
胶囊一般是指具有空腔结构的单元体。纳米颗粒若具有空腔结构，也可称谓纳米胶囊。例如，以β-FeOOH纳米棒为模板，逐次采用包硅、加热、还原和去除模板等工序后，便可以获得α-Fe2O3和Fe3O4纳米胶囊。但是，这类制备氧化铁纳米胶囊的工艺比较复杂，制备成本高。
发明内容
针对现有技术中所存在的不足之处，本发明提供了一种β-FeOOH纳米胶囊的制备方法。
为了实现上述目的，本发明所采用的技术方案为：一种β-FeOOH纳米胶囊的制备方法，首先利用氯化铁水溶液水解生成β-FeOOH纳米棒，接着利用β-FeOOH纳米棒、甘油和水升温醇热熟化制备β-FeOOH纳米胶囊。
作为本发明制备方法的优选技术方案，利用氯化铁水溶液水解生成β-FeOOH纳米棒的方法为：称取0.27～5.4g的FeCl3.6H2O溶于100mL的去离子水中配成氯化铁水溶液，缓慢加热到90～95℃，通过水解反应48～144h后得到β-FeOOH纳米棒。
作为本发明制备方法的进一步优选技术方案，利用β-FeOOH纳米棒制备β-FeOOH纳米胶囊的方法为：将0.5～1.5g的β-FeOOH纳米棒转入反应釜中，加入20mL的甘油和1～5mL的水，升温至180℃反应6～48h即可获得β-FeOOH纳米胶囊。
本发明以绿色、环保的甘油为反应介质，以β-FeOOH纳米棒为前驱体，采用醇热熟化处理技术成功得到了β-FeOOH纳米胶囊。此方法具有操作简单、成本低廉、获得产物可见光吸收性能优异等特点，为制备胶囊型纳米颗粒提供了一种简易和环保的方法。
和现有技术相比，本发明还具有以下优点：
1)、实现了β-FeOOH内部结构调控转变，为多孔结构的纳米材料的制备提供了一种新的方法。
2)、本发明方法具有实验操作简单、成本低廉，获得的产物量大的特点。
附图说明
图1为实施例1制备产物的形态和结构；
图2为实施例2制备产物的形态和结构；
图3为实施例1和2制备产物的可见-紫外吸收曲线。
具体实施方式
以下结合实施例和附图对本发明的β-FeOOH纳米胶囊的制备方法作出进一步的详述。本发明方法所得沉淀物的结构、形态性能分别采用X射线粉末衍射(XRD，D3500)和场发射扫描电子显微镜(FEI，Sirion 200)来表征和分析。
实施例1：纺锤形β-FeOOH纳米棒的制备及表征
称取0.5g的FeCl3.6H2O溶于100mL的去离子水中配成氯化铁水溶液，缓慢加热到95℃，通过水解反应72h后得到β-FeOOH纳米棒。
利用SEM和TEM分别对产物的形态和结构进行研究可知，获得的产物形貌为纺锤形(见图1a和图1c)，结合产物XRD分析可知(见图1b)，产物为β-FeOOH(XRD标准谱图：PDF#34-1266)，产物的可见-紫外吸收最大波长约为362nm(见图3虚线)。
β-FeOOH的形成可以看成经过以下两个过程：首先，Fe3+发生水解反应生成了亚稳态Fe(OH)3胶体；接着，Fe(OH)3失水形成了β-FeOOH，上述两过程可以用式子(1)和(2)分别表示：
通常，纺锤形β-FeOOH纳米棒的形成是在酸性且含有氯离子的环境中进行的。
实施例2：β-FeOOH纳米胶囊的制备及表征
将1g的β-FeOOH纳米棒转入反应釜中，加入20mL的甘油和2mL的水，升温至180℃反应12h即可获得β-FeOOH纳米胶囊。
首先，利用SEM和TEM分别对获得产物的形态和结构进行分析，可以看出，β-FeOOH纳米棒经过醇热处理后，其外形基本保持不变，仍然是纺锤形状(见图2a)，而TEM观察则表明，实心的β-FeOOH纳米棒已转变成为空心的纳米胶囊(见图2c)。XRD分析结果进一步证实(见图2b)，β-FeOOH纳米棒向β-FeOOH纳米胶囊转变时，发生了同素异构转变现象。对比图1d和图2c可知，β-FeOOH纳米棒(10.53×10.53×3.03)在转变为β-FeOOH纳米胶囊(10.48×10.48×3.023)后，其晶胞尺寸将有所变小，这说明了纳米棒转变为纳米胶囊后，纳米棒体内发生了收缩效应，即宽松的层状β-FeOOH纳米棒在甘油中可能发生了断层、层重组与合并等导致空化的行为，从而形成了胶囊结构。
据文献报道，纺锤形β-FeOOH纳米棒表面包覆一层SiO2后，通过加热处理(～600℃)后，也将从体内发生空化效应，从而形成了α-Fe2O3纳米胶囊。而本发明发现β-FeOOH纳米棒在180℃的甘油中发生空化效应为首次发现。形成的β-FeOOH纳米胶囊的可见-紫外最大吸收波长约为375nm(见图3，实线)，和β-FeOOH纳米棒的可见-紫外最大吸收波长362nm相比，向长波方向移动了约10nm左右，即发生了蓝移现象。
以上内容仅仅是对本发明的构思所作的举例和说明，所属本技术领域的技术人员对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，只要不偏离发明的构思或者超越本权利要求书所定义的范围，均应属于本发明的保护范围。
