Abstract

Graphene/tungsten oxide composite sensitive material is prepared by solvothermal method.The structure and morphology of the composite materials are characterized by XRD

SEM and Raman.The results show that the prepared tungsten oxide present tubular structure

and graphene dispersed in the sensitive material.Graphene/tungsten oxide（WO

） sensing material is coated on the interdigital electrode to make a sensor for gas sensing performance measurement.The results show that the sensor can detect NO

at room temperature with a detection limit of 1×10

-6

;the response time is about 400s w

ith volume fraction of 3×10

-6

;and NO

can be detected in the atmosphere of NH

OH and CH
