氧化铁（Fe2O3）是一种重要的n型半导体材料,被广泛应用于染料、废水处理、光催化和锂离子电池等领域。采用水热法合成了不同直径大小的片状结构的α-氧化铁,其中大尺寸的片状α-氧化铁在1 000 ℃仍能保持原有的表观颜色和形态,证明了其具有高热稳定性,在油漆、染料等领域具有较大的应用潜力。研究了氢氧化钠与三氯化铁溶液浓度及其混合顺序对α-氧化铁材料性能的影响,并且分析了片状α-氧化铁的带隙、锂离子电池性能及粉体表观颜色与颗粒尺寸的依赖关系。结果表明,通过调整氢氧化钠溶液的浓度和氢氧化钠与三氯化铁的滴加顺序可以得到不同尺寸的片状α-氧化铁,α-氧化铁的颜色随着其颗粒尺寸的增大而加深,带隙随着颗粒尺寸的减小呈现上升趋势,并且纳米级颗粒相对于微米级颗粒会提高锂离子电池的实际容量。该研究有助于研发α-氧化铁的宏量制备工艺及发掘其在电化学、陶瓷釉料、颜料等方面的应用,对降低传统能源活动的碳排放、推动中国早日实现“双碳”的国家目标具有重要的意义。

Ferric oxide（Fe2O3） is an important n-type semiconductor material,which has been widely used in the fields of dyes,sensors,wastewater treatment,photocatalysis and lithium ion batteries.α-Fe2O3 with different sizes of flake structures was synthesized by hydrothermal method.The large size of flake α-Fe2O3 could still retain its original color and shape at 1 000 ℃,which proved that it had high thermal stability and had great application potential in paint,dye and other fields.The effect of NaOH and FeCl3 solution concentration and mixing order on α-Fe2O3 materials was studied.Moreover,the band gap,lithium storage performance and the dependence of powder color and size were analyzed.The results showed that flake α-Fe2O3 with different sizes could be obtained by adjusting the NaOH concentration and NaOH/FeCl3 adding sequence.The color of α-Fe2O3 deepened with the increase of particle size,and the band gap increased with the decrease of the particle size.Moreover,the actual capacity of the battery could be improved by dozens of nano-sized particles compared with micron size particles.It would provide the benefit to the research and development of the macro-preparation process of α-Fe2O3 and the application of electrochemistry,ceramic glazes,pigments.More importantly,the development of α-Fe2O3 was of great significance for reducing carbon emissions from traditional energy activities and promoting China′s early realization of the“dual carbon” national goal.
