Abstract: As a typical sensitive material, nanometer tungsten trioxide(WO3) has been developed in biology, chemistry and military affairs extensively. The gas sensing properties of WO3 can be greatly improved through the structure design and appearance modification. The preparation technology of nanometer WO3 with different appearances and its current research situation on gas sensors in recent years are introduced. Finally, the problems existed in research process are pointed out.
