Gas-sensing selectivity of n-ZnO/p-Co3O4 sensors for homogeneous reducing gas
Abstract
Abstract Poor selectivity has always been the most severe challenge in the practical applications of gas sensors based on metal-oxide semiconductors (MOSs). It is difficult to distinguish CO and H2 because of the cross-sensitivity phenomenon. Herein, a series of n-ZnO/p-xCo3O4 NPs (1:x represents the molar ratio of Zn:Co) was prepared through a simple sol-gel method. Structural and material characterization were performed via X-ray diffraction (XRD) and transmission electron microscopy (TEM), while other techniques were used to assess the gas-sensing properties. The characterization results indicated that the oxides in the n-ZnO/p-0.61Co3O4 NPs formed p-n heterojunction instead of being dissolved together. The gas sensing results confirmed that the Zn:Co molar ratio influenced the gas-sensing selectivity of the n-ZnO/p-xCo3O4 NPs. Interestingly, regarding the gas-sensing behavior of n-ZnO/p-0.61Co3O4 NPs, the overall conductance of the film decreased in the presence of CO and increased in the presence of H2 at the testing temperature of 350 °C. This paper provides an approach to address the problem of poor selectivity of MOS-based gas sensors.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
