Description
技术领域
本发明涉及一种Fe2O3微观结构的制备方法,具体涉及一种中空球状Fe2O3微观结构的制备方法。
背景技术
Fe2O3具有n型半导体的特性,化学稳定性好,具有较高的催化性能,良好的耐光性、耐久性并且对紫外线有一定的屏蔽作用,Fe2O3制备成本低廉,被广泛应用于光催化、装饰材料、气敏传感器、光电学仪器、以及磁性材料等领域。在氧化还原反应中,铁的价态会发生变化,在水溶液中,会发生催化氧化反应,如Fenton反应。20世纪50年代以来,科研人员探究了许多的类Fenton反应。20世纪90年代以后,重点研究了类Fenton反应的污水处理模型,选择三价铁的草酸盐配合物作为典型代表。当溶液中加入过氧化氢时,会产生强烈的催化氧化反应,所以说,Fe2O3纳米颗粒在催化性能方面应用前景广阔。
由于纳米Fe2O3晶体中的晶格缺陷,位于缺陷处的三价铁为不饱和状态,容易吸收含有多余电子的物质形成配合体从而达到稳定状态。为此,徐宏, 刘剑洪, 陈沛, 赵凤起,田德余在火炸药学报 2002 (03)中报道利用纳米Fe2O3催化火药的热分解反应,二价铁与火药分子形成多元配合物,而纳米氧化铁比表面积较大,能够吸收分解过程中产生的气体,促进放出热量并且能够使分解反应反应完全。Fe2O3可以吸附空气中的有害气体。在化工生产中,常用作除去H2S的有效试剂。它的主要特征是在低温条件下就可以迅速再生,实现对H2S吸附的循环应用。开始反应初期,S2- 和SH-代替O2-离子,对于表面羟基的存在并无影响。Gaurav Jain, Mahalingam Balasubramanian, and Jun John Xu等人在Chem. Mater.,2006, 18 (2), pp 423-434 中报道运用低温溶液合成法制备了Fe2O3纳米晶,粒径较小,也有较好的吸附性能。
目前,通过合理设计反应体系与反应过程,制备具有特殊形貌的Fe2O3微纳米材料并研究相关物化性能仍然是该领域的研究热点。
发明内容
本发明的目的是提供了一种Fe2O3微观结构的制备方法。该制备方法操作简单,无需惰性气体保护,原材料价格低廉,合成过程简便,生产成本低。本发明所得Fe2O3的微观结构形貌可控,尺寸分布范围窄,产率高,重复性好,在光催化、装饰材料、气敏传感器、光电学仪器、以及磁性材料等领域具有潜在的应用价值。
本发明以亚铁氰化钾为铁源,加入多元醇溶液中,然后用溶剂热反应,离心洗涤后得到Fe2O3微观结构。该方法能够较为简单、可控的得到中空球状Fe2O3微观结构,具有很好的工业化应用前景。
具体技术方案如下:
一种中空球状Fe2O3微观结构的制备方法,包括以下步骤:
(1)将亚铁氰化钾(K4Fe(CN)6·3H2O)加入到多元醇的混合溶剂中,加入碳酸氢钠和尿素,搅拌1h得到分散均匀的溶液;
(2)将上述溶液转移到反应釜中进行溶剂热反应;
(3)反应完全后,将产物沉淀、离心分离、洗涤,得Fe2O3微观结构。
通过本发明的方法,可以很容易的得到中空球状Fe2O3微观结构。
上述步骤(1)中,所述多元醇为丙三醇和异丙醇,丙三醇和异丙醇的体积比为1:1.5-2.5。
上述步骤(1)中,亚铁氰化钾、尿素和碳酸氢钠的摩尔比为1:1.4-1.6:9.6-10.4。
上述步骤(1)中,亚铁氰化钾在混合溶剂中的浓度为0.01-0.02 mol/L。
上述步骤(2)中,溶剂热反应温度为160-200℃,反应时间8-12h。
上述步骤(3)中,所得产物为中空球状Fe2O3微观结构,该球状结构直径为150-350nm。
本发明上述方法中,通过设计合适的反应体系,以异丙醇和丙三醇作为混合溶剂,通过调整溶剂加入比例,亚铁氰化钾、尿素和碳酸氢钠的的加入比例等,利用溶剂热法一步合成了形貌均一的中空球状Fe2O3微观块体结构,可控性强。亚铁氰化钾、尿素和碳酸氢钠的摩尔比,以及反应所用的溶剂体系(醇体系)对Fe2O3形貌的形成有重要作用,通过它们的配合,可以得到所需的形貌结构。此外,通过调整溶剂热法的温度和时间也可以使产物的形貌更为规整、尺寸分布更窄。
本发明经过大量的理论分析与实验设计及验证过程,通过控制反应体系的成分和含量、反应温度、反应时间等,得到了结构稳定、形貌可控、重复性好的的中空球状Fe2O3微观结构。本发明所用原料均为市场常见化学药品及试剂,价格低廉,合成过程简便,无需惰性气体保护,生产成本低,所得中空球状Fe2O3的微观形貌可控,产物产量高、纯度高、形貌均一、尺寸分布范围窄,在光催化、装饰材料、气敏传感器、光电学仪器、以及磁性材料等领域具有潜在的应用价值。
