以K4[Fe(CN)6]、PEG400和H2O2为原料,通过水热法制备了树枝状α-Fe2O3,并采用XRD、SEM、TEM、SAED和Raman技术对其微观形貌和结构进行了分析。研究发现α-Fe2O3树枝的主干生长方向为[101-0],分枝的生长方向为[11-00]和[011-0],进一步对树枝状α-Fe2O3的生长过程和形成机理进行了讨论。

The dendritic α-Fe2O3 has been synthesized using K4[Fe(CN)6],polyethylene glycol(PEG400) and H2O2 as raw materials by hydrothermal method.The morphology and microstructure of the product have been characterized by XRD,SEM,TEM,HRTEM,SAED,and Raman.It has been revealed that the main trunk of α-Fe2O3 grows along while the branches grow along and .Furthermore,the growth process and formation mechanism of the products have been discussed.
