Description
技术领域
本发明涉及无机非金属功能材料技术领域，更具体的说是涉及一种磁性Bi25FeO40纳米材料的制备方法及催化应用。
背景技术
过去几十年，工业化和城市化进程消耗了庞大的石化资源，造成了严重的资源匮乏和环境污染，这是当今世界各国亟待解决的两大主题。许多有毒有害的有机污染物具有致癌、致畸、致突变性，如四环素抗菌素由于其生物活性能产生抗药性细菌和诱导许多类生物体的不理想的生物反应，被认为是潜在的微污染物。这些抗菌素广泛用于人类和牲畜的疾病控制，排泄物或处理的过期药物最终沉入水和土壤中，然而通过传统的生物降解难以去除。高级氧化技术以产生具有强化能力的活性自由基为特点，在高温高压、电、声、光辐照、催化剂等反应条件下，使其降解成低毒或者五毒的小分子物质，在有机污染物处理方面显示出其独特的优势。Bi25FeO40具有窄的带隙～2.8eV、可变价的Fe2+/Fe3+离子及铁磁特性，其纳米材料显示出较高的可见光-芬顿催化活性，且外加磁场可实现分离和回收，引起科研人员的广泛关注。
发明内容
有鉴于此，本发明针对有毒有害的有机污染物难以去除的问题及环境保护的迫切需求，提出了一种方法简单、反应条件易控，条件较温和、绿色无污染的制备方法；同时，利用其窄的带隙～2.8eV、可变价的Fe2+/Fe3+离子，可见光-芬顿反应降解抗菌素。
为了达到上述目的，本发明采用如下技术方案：
一种磁性Bi25FeO40纳米材料的制备方法及催化应用，制备过程如下：
(1)将0.01–0.05mol硝酸铋、硝酸铁溶于80ml去离子水中，经搅拌、超声制得A溶液；
(2)将0.01–0.05mol表面活性剂P123溶于30ml乙醇中，经搅拌制得B溶液；
(3)将A溶液逐滴加入到B溶液中，经搅拌制得A+B混合溶液；
(4)将40ml浓度为0.1-0.75M的KOH溶液逐滴加入A+B混合溶液，经搅拌、超声制得前驱体溶液；
(5)将前驱体移至带有聚四氟乙烯内衬的反应釜中，150–240℃水热反应2-24h；
(6)反应完成后，洗涤、离心直至无泡沫为止，经干燥得到磁性Bi25FeO40纳米粉体。
此外，本发明还要求保护上述一种磁性Bi25FeO40纳米材料在可见光-芬顿反应解盐酸四环素方面的应用，其特征在于：所述Bi25FeO40纳米粉体和过硫酸氢钾在20min氙灯可见光照射下对盐酸四环素的降解率达到85％左右。
本发明具有以下有益效果：
本发明制备方法简单、反应条件易控，条件较温和、绿色无污染；同时，可见光-芬顿反应能快速降解抗菌素，解决抗菌素难以生物降解的问题，避免因抗菌素的生物活性而对环境造成污染。
