| Abstract: | A serial of nanometer materials were synthesized W,the structure and crystal phase of the powders were characterized on an X-ray diffractometer;the shape and size were analyzed with the help of JSM scan electron microscopy or JEM Transmission electron microscopy.The product powders were made up gas sensors and gas sensitivities of these materials to different gas were tested on the gas-sensing propertied testing instrument.Respond that 0.33WO3-Fe2O3 and 0.5WO3-Fe2O3,have higher sensitivity to oxidizing gas(... |
