| Abstract: | The Fe2O3 hollow microspheres were successfully prepared by a glucose-assisted hydrothermal approach at 180 ℃,and followed by calcination at 500 ℃ for 4 h.The structure of Fe2O3 hollow microspheres was studied by XRD and SEM.The results show that the products were pure Fe2O3 with a hexagonal structure.And the microspheres with a diameter of 1~2 μm were assembled by Fe2O3 nanoparticles(50~100 nm);the surface of Fe2O3 hollow microspheres densified with the increasing of glucose concentration.Above all,the gas sensing properties of the sensors based on the Fe2O3 hollow microspheres were investigated,which can improve the sensitivity of the gas sensor. |
