Abstract

The present investigation deals with the preparation of CO sensor based on SnO2. In this work, SnO2 films were prepared by standard screen-printing method. These films were characterized by x-ray diffraction (XRD) measurements, spectroscopy and scanning electron microscopy (SEM). These films exhibit high sensitivity, excellent selectivity, fast response and recovery to CO gas at 300 oC in air atmosphere..
