SnO based sensors has received extensive attention in the field of toxic gas detection due to their excellent performances with high sensitivity, fast response, long-term stability. Volatile organic compounds (VOCs), originate from industrial production, fuel burning, detergent, adhesives, and painting, are poisonous gases with significant effects on air quality and human health. This mini-review focuses on significant improvement of SnO based sensors in VOCs detection in recent years. In this review, the sensing mechanism of SnO-based sensors detecting VOCs are discussed. Furthermore, the improvement strategies of the SnO sensor from the perspective of nanomaterials are presented. Finally, this paper summarizes the sensing performances of these SnO nanomaterial sensors in VOCs detection, and the future development prospect and challenges is proposed.
