摘 要：A new gas sensor with high response and selectivity was fabricated by using molecularly imprinted powders(MIPs)which provide special recogni-tion sites to *** MIPs were characterized by X-ray diffraction(XRD),fourier transform infrared spectrometer(FT-IR)and transmission electron microscopy(TEM),*** gas sensing properties of MIPs to methanol were *** experimental results indicate that the sensors based on the MIPs show excellent gas sensing properties to methanol vapor,and the properties of the sensor with x=6:10(x=methyl acrylic acid:LaFeO,molar ratio)are the *** the optimal operating temperature of130℃,the response of the sensor(x=6:10)to 1 ppm methanol is 21,and the response and recovery times are 57 s and 67 s,respectively.
