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。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.,Fe^3＋/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.
