我们系统地研究了溶剂在高压罐分解乙酰丙酮铁以合成纳米氧化铁中的作用。溶剂官能度的细微变化导致纳米颗粒形态的显著差异，包括单分散球体、六角形小片、化合物立方体和更大的分级结构。能够与铁螯合的溶剂对纳米粒子的生长具有最大的影响，而侧链的添加扰乱了纳米粒子在生长中的竞争吸附，从而提供了一种新的形态控制手段。
We present a systematic study of the role of the solvent in the autoclave-based decomposition of iron(III) acetylacetonate to synthesise iron oxide nanoparticles. Subtle variations in solvent functionality yield substantial differences in nanoparticle morphology, spanning monodisperse spheres, hexagonal platelets, compound cubes and larger hierarchical structures. Solvents capable of chelation to iron afford the greatest influence over nanoparticle growth, whilst addition of side-chains to the solvent perturb competitive adsorption on growing nanoparticles to provide a new means of morphological control.
