The Role of Zn Ions in the Structural, Surface, and Gas-Sensing Properties of SnO₂:Zn Nanocrystals Synthesized via a Microwave-Assisted Route.

ABSTRACT: Although semiconducting metal oxide (SMOx) nanoparticles (NPs) have attracted attention as sensing materials, the methodologies available to synthesize them with desirable properties are quite limited and/or often require relatively high energy consumption. Thus, we report herein the processing of Zn-doped SnO₂ NPs via a microwave-assisted nonaqueous route at a relatively low temperature (160 °C) and with a short treatment time (20 min). In addition, the effects of adding Zn in the structural, electronic, and gas-sensing properties of SnO₂ NPs were investigated. X-ray diffraction and high-resolution transmission electron microscopy analyses revealed the single-phase of rutile SnO₂, with an average crystal size of 7 nm. X-ray absorption near edge spectroscop
