摘要：In the present work the authors have fabricated copper oxide nanoparticles through a water bath method and investigated their composition and microstructure using XRD and TEM methods. Their electrical properties were investigated under different atmospheres and temperatures after painting them onto the insulating substrates with interdigital Pt and Au electrodes. The electric currents are found dramatically dependent on the variation of humidity, temperature, and ratio of oxygen to nitrogen. In the end, the HCHO gas sensitivity of these nanoparticles has been investigated.
