以铁箔为原材料和基片,通过控制热氧化过程中的宏观实验条件(载气流量及其组分、压强、温度分布和反应时间等),实现了α-Fe2O3一维纳米结构的可控生长,获得了大面积(10mm×10mm)、单分散性好、沿[110]方向生长的α-Fe2O3纳米带或纳米线阵列.对不同宏观实验条件下所制备的样品进行形貌和晶格结构表征和分析,认为热氧化过程中α-Fe2O3一维纳米结构的生长遵循类似气-固机制的顶端生长模式,生长点铁原子和氧原子比是控制α-Fe2O3一维纳米结构生长的关键因素. By controlling the macroscopic experimental conditions (carrier gas flow, composition, pressure, temperature distribution and reaction time) in the process of thermal oxidation, a one-dimensional nanostructure of α-Fe2O3 was controlled by using iron foil as raw material and substrate (10mm × 10mm), a-Fe2O3 nanoribbons or nanowire arrays with good monodispersion and growth along the [110] direction were obtained.The morphology and lattice of the samples prepared under different macroscopic experimental conditions It is considered that the growth of α-Fe2O3 one-dimensional nanostructures followed the apical growth mode similar to the gas-solid mechanism during the thermal oxidation. The iron atom and oxygen atomic ratio of growth points are the key factors controlling the growth of α-Fe2O3 one-dimensional nanostructures factor.
