 摘要: 采用一步水热法,实现了对铁醇盐各种多级结构的可控合成。通过改变反应条件(如:Fe3+与尿素的物质的量比,铁离子价态,反应时间以及反应温度)成功合成了球状、竹节状、纱球状、花状、燕窝状、豆瓣状、薄片状、纸团状和层状结构。此外,还着重研究了花状铁醇盐的储锂性能,并在反应前驱体(如金属醇盐)中寻找锂电负极替代材料。

Abstract: A detailed study on the controllable synthesis of iron alkoxides hierarchical structures was carried out via a facile onepot hydrothermal procedure. By varying the reaction system conditions (e.g., Fe3+/urea ratio, valence state of iron ions, reaction time and reaction temperature), spheroidal, bamboolike, yarnball like, flowerlike, cubiloselike, watercresslike, flakelike, spitballlike and microlayered structures were successfully synthesized. Additionally, the lithium storage properties of flowerlike iron alkoxides were also investigated, which established a precedent to search for alternative anode materials within the scope of reaction precursors (e.g., metal alkoxides) for lithiumion batteries.

Key words: iron alkoxides; controllable synthesis; hierarchical structures; lithium storage properties
