Abstract: 
Nanostructured ZnO particles were prepared through a straightforward, quick and low-temperature synthesis route involving coprecipitation of the metal precursor salts with oxalic acid, followed by hydrothermal treatment at 135 or 160 degrees C. The synthesised nanostructured powders were thoroughly characterised by a wide array of analytical techniques from the morphological (Scanning Electron Microscopy -SEM-, Transmission Electron Microscopy -TEM-, Energy-dispersive X-ray Spectroscopy -EDXS-), structural (Powder X-ray Diffraction -PXRD-, Selected Area Electron Diffraction -SAED-), compositional (X-ray Photoelectron Spectroscopy -XPS-) and physical (thermal stability) point of view. As far as functional applications are concerned, the powders were tested as gas sensor materials for H2S detection. Thereby these ZnO particles showed unexpected gas dosimeter behaviour at 150 degrees C. Based on these observations and on a comparison with literature a new model for the interaction of ZnO nanostructures with H2S is proposed.
