Zn2SnO4 nanoparticles were synthesized by a facile hydrothermal method for a C2H5OH gas-sensing application. The synthesized materials were characterized by field-emission scanning electron microscopy, powder x-ray diffraction and Raman spectroscopy. Gas sensing characteristics were measured at various concentrations of C2H5OH in temperature ranging from 350 to 450º C. | Hydrothermal synthesis of Zn2SnO4 nanoparticles for ethanol sensor
