一种简单调控四氧化三铁纳米粒子形貌的方法
摘要：
一种简单调控四氧化三铁纳米粒子形貌的方法是将二价铁盐和三价铁盐溶于水中，再加入NaOH，将pH值调节至10-12，搅拌，得四氧化三铁，过滤，用水和乙醇交替清洗，干燥后得到球状四氧化三铁纳米粒子；将二价铁盐和三价铁盐溶于水中，再加入十二烷基硫酸钠和NaOH，将pH值调节至10-12，并在可见光光源下照射，得四氧化三铁，过滤，用水和乙醇交替清洗，干燥后得到立方体状的四氧化三铁纳米粒子或棒状四氧化三铁纳米粒子。本发明具有相对简单、生产成本低廉、形貌易调控，易于实现规模化的优点。
摘要（英）：

The invention relates to a method for simply regulating ferroferric oxide nanoparticle morphology. The method comprises: dissolving a ferrous iron salt and a ferric iron salt into water, adding NaOH, adjusting the pH value to 10-12, stirring to obtain ferroferric oxide, filtering, alternately washing with water and ethanol, and drying to obtain spherical ferroferric oxide nanoparticles; and dissolving a ferrous iron salt and a ferric iron salt into water, adding sodium dodecyl sulfate and NaOH, adjusting the pH value to 10-12, irradiating under a visible light source to obtain ferroferric oxide, filtering, alternately washing with water and ethanol, and drying to obtain cube-shaped ferroferric oxide nanoparticles or rod-like ferroferric oxide nanoparticles. The method has advantages of relative simpleness, low production cost, easy morphology control, and easy scalization achievement.
