Perovskite halide materials are currently attracting considerable attention owing to their superior optical and electrical properties. This study proposes a reliable process for synthesizing hybrid nanomaterials made of methylammonium tin iodide (MASnI3) submicron spheres and tin dioxide (SnO2) nanowires. Post-fabricated hybrid nanomaterials were investigated for NO2 sensing properties at 25°C in the dark. The effect of moisture on the NO2 sensitivity of this material was investigated. The durability of sensor components using this material was also investigated. In this paper, we also discuss the NO2 sensitivity mechanism of MASnI3/SnO2 hybrid nanomaterials in detail.
