Abstract

The organic/MoO3 hybrid sensors show a distinct response to aldehyde gases, formaldehyde and acetaldehyde, by changing the electrical resistance, whereas they show almost no response to other VOCs. The organic/MoO3 hybrids have a potential for selective VOC detection because the sensing properties of organic/MoO3 hybrids can be controlled by the kind of interlayer organic components. In this study, we have carried out the detail characterization of the interlayer of the organic/MoO3 hybrids as well as the valence of Mo and evaluation of their sensing properties.
