| Abstract: | The preparation of Fe doped In2O3 nano-powder using a hydrothermal method is introduced.Its size,phase and morphology are analyzed by XRD,SEM and TEM.The gas sensing characteristics of the materials are tested in static slate.The results show that the morphology of the In2O3 with mass fraction 7% Fe is rods with good dispersity.The average length of the as-synthesized rods is about 300～500nm,and the width is 20 nm.The In2O3 with mass fraction 7% Fe has the highest sensitivity as high as 182.75 to 100×10-6 Cl2 at lower working temperature 125℃.And the In2O3 with mass fraction 7% Fe also has a high sensitivity as high as 17.9 to 10×10-6 Cl2 at 125℃.So the sensors can tests low volume fraction of Cl2.The sensor based on In2O3 also has satisfied selectivity,quick response and recover. |
