【摘要】 合成了一种新型的具有单晶结构的α-Fe2O3纳米晶(NFO-1).在我们的合成方法中,样品的形貌和结构在低反应浓度体系中运用无机盐和有机模板进行双重调控,同时用溶剂挥发诱导自组装(EISA)来加速反应和在不改变形貌结构的前提下获得高产率样品.所得α-Fe2O3纳米晶的形貌和结构对其表面修饰功能有明显的影响,NFO-1因其特殊的纺锤状形貌而与表面功能试剂(多巴胺)之间的化学作用有明显的增强.并且,本文所描述的合成方法同样适用于其他过渡金属氧化物纳米单晶的合成.我们预期,这种方法可为新型纳米材料的合成提供新的途径.更多还原

【Abstract】 We synthesized novel α-Fe2O3 nanocrystals (NFO-1) with single crystalline structure. In our synthe strategy, the morphology and structure can be controlled simultaneously by the choice of inorganic salt (IS) and orga template (OT) in the extremely low precursor concentration reaction system. The evaporation-induced self-assem (EISA) method was used to accelerate the reaction and to recover the synthesized α-Fe2O3 with high yields wh preserving its favorable shape and structure. The morphologies and structures of the obtained α-Fe2O3 nanocrys greatly influence their surface functionalization capability. The chemical interaction between NFO-1 and the surf functionalization agent (dopamine) was obviously enhanced because of its special spindle-like morphology. The synthe method described in this paper is suitable for the synthesis of other transition metal oxide single nanocrystals as w and we expect that this new route will be useful for the synthesis of novel nanomaterials.更多还原
