Methanal and xylene sensors based on ZnO nanoparticles and nanorods prepared by room-temperature solid-state chemical reaction

Easy synthesis of ZnO nanoparticles and nanorods were executed by solid-state chemical reaction between ZnCl2 and NaOH under ambient condition. The methanal (HCHO) and xylene (C6H4(CH3)(2)) sensing characteristics of as-prepared ZnO products were investigated. The ZnO products exhibited good HCHO and C6H4(CH3)(2) sensing properties at relatively low working temperature, which can be regarded as excellent potential candidates for HCHO and C6H4(CH3)(2) sensors.
