Synthesis of nanocrystalline ZnS/TiO2 films for enhanced NO2 gas sensing
Thin Solid Films（2020）
Abstract
•Impregnation of porous titania with unimolecular zinc bis(benzyl)thiol precursor.•Synthesis of ZnS nanocrystals in porous titania matrix by thermolysis.•Gas sensor device based on the ZnS/TiO2 nanocomposite films.•NO2 gas detection down to 1 ppm with negligible response to reducing gases (CO, CH4).
