丙酮的响应值为48.5，是纯NiFe

传感器响应值的2倍，具有更加优异的气体敏特性。

Abstract

Carbon nanotubes(CNTs)-Ni/Fe precursor composites are synthesized by the solvothermal method and calcined to obtain NiFe

.The micromorphology

crystal structure and specific surface area of the samples are characterized in detail by scanning electron microscopy(SEM)

transmission electron microscopy(TEM)

X-ray diffractometer(XRD)and N

-physical adsorption analyzer.Subsequently

the above materials are made into sensors to test the gas-sensing properties for acetone.Experimental results show that the sensor based on NiF

which is doped with 40mg and calcined at 600℃

exhibits a response value of 48.5 toward to acetone with a volume fraction of 100×10

-6

at 270℃

which is twice that of the pure NiFe

sensor and has better gas-sensing properties.
