摘要 用阳离子型表面活性剂十六烷基三甲基溴化铵(CTAB)为模板剂、[FeF6]3-为铁源、氨水为沉淀剂合成了介孔-βFeOOH(四方纤铁矿)粒子。对所合成的介孔氧化铁粒子用红外光谱(IR)、粉末X-射线衍射(XRD)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)、热重-差热分析(TG-DSC)、氮气吸附脱附(BET)等手段进行了表征。结果表明,介孔氧化铁粒子具有不规则椭球状形貌、虫孔状介孔结构,比表面积达164.4 m2/g,用乙醇萃取可以完全除去所使用的表面活性剂模板。 Mesoporous β-FeOOH(akaganeite) particles were prepared by a surfactant-templating method,using a complex ion 3-as inorganic source;ammonia as precipitant and cationic surfactant(CTAB) as template.Washing by Soxhlet extraction with ethanol could eliminate the template surfactant.The particles were characterized by Fourier transform infrared(IR),powder X-ray diffraction(XRD),transmission electron microscopy(TEM),thermogravimetric analysis and differential scanning calorimetry(TG-DSC),as well as Brunauer-Emmett-Teller surface(BET) area measurement.The mesoporous particles were irregularly ellipsoidal in shape and there were wormhole-like mesopores in each ellipsoidal particle.The surface area of mesoporous akaganeite particles was 164.4 m2/g.
