Simple Preparation of Well-Dispersed Nanosized α-Fe2O3

Well-dispersed α-Fe2O3 nanocrystalline was prepared by a convenient self-propagation combustion method using low-toxic glycine as fuel, low-cost Fe (NO3)2·9H2O as raw materials. The XRD results indicate that the glycine doses have an important effect on the control of the average size and the order...

Zusammenfassung:Well-dispersed α-Fe2O3 nanocrystalline was prepared by a convenient self-propagation combustion method using low-toxic glycine as fuel, low-cost Fe (NO3)2·9H2O as raw materials. The XRD results indicate that the glycine doses have an important effect on the control of the average size and the order of the crystalline phase. The UV-vis results indicate that the α-Fe2O3 nanocrystals prepared by this method have a broad absorption peak whose center is at about 221 nm. TEM images revealed that the products were composed of well-dispersed particles with an average size about 35 nm.
