一种Fe3O4@C@TiO2磁分离光催化剂的简易制备方法
摘要：
本发明涉及一种Fe3O4@C@TiO2磁分离光催化剂的简易制备方法，包括以下步骤：1)取β‑FeOOH纳米棒，分散于水中形成分散液；2)以间苯二酚、甲醛合成FeOOH@RF核壳纳米棒，分散于乙醇中形成分散液；3)加入乙醇和CH3CN以及氨水搅拌混匀组成A液；另取乙醇和CH3CN混匀加入TBOT组成B液，混合，室温反应一定时间即合成纳米棒；4)通过高温煅烧，即得。本发明的有益效果在于：利用简易、温和的方法制备了磁响应可回收的Fe3O4@C@TiO2可见光纳米光催化剂。该合成方法操作简单，同时设备要求低，制备的Fe3O4@C@TiO2的核壳结构的纳米棒分散性较好，纳米粒子尺寸比较均匀。
摘要（英）：

The invention relates to a simple preparation method for a Fe3O4@C@TiO2 magnetic separation photocatalyst. The method includes steps: 1) taking beta-FeOOH nanorods, and dispersing into water to form dispersion liquid; 2) adopting resorcinol and formaldehyde for synthesizing FeOOH@RF core-shell nanorods, and dispersing into ethyl alcohol to form dispersion liquid; 3) adding ethyl alcohol, CH3CN and ammonium hydroxide, and well stirring and mixing to form liquid A; taking ethyl alcohol and CH3CN again, well mixing, and adding TBOT to form liquid B; mixing for room-temperature reaction for a certain time to obtain the nanorods; 4) performing high-temperature calcinations to obtain the Fe3O4@C@TiO2 magnetic separation photocatalyst. The method has advantages that the magnetic-response recyclable Fe3O4@C@TiO2 visible-light nanometer photocatalyst is prepared according to the simple and mild method; the method is simple in operation and low in equipment requirement, and the prepared Fe3O4@C@TiO2 core-shell nanorods are high in dispersity and uniform in nanoparticle size.
