Abstract α-Fe2O3 and SnO2 doped α-Fe2O3 were made by chemical precipitation and hydrolysis. Effects of doping methods on microstructure of α-Fe2O3 were studied with XRD and TEM. Effects of doping methods on gas sensitivity and resistance of α-Fe2O3 were tested wit

Key words: Fe_2O_3 doping method hydrolysis chemical co-precipitation gas-sensing properties
