In this paper the authors present the characterization of CO resistive sensors based on Pd modified YCoO3 perovskite, mainly addressed to its cross-sensitivities to different gases. In particular, sensors based on YCo0.95Pd0.05O3 and on YCo0.90Pd0.10O3 in addition to those based on 1% Pd supported on YCoO3 were tested; this materials showed a good performance at relatively low temperatures in terms of both CO sensitivity and response speed. The proposed sensors were tested with mixtures of...
