ABSTRACT=<p>SnO<sub>2</sub> 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<sub>2</sub> based sensors in VOCs detection in recent years. In this review, the sensing mechanism of SnO<sub>2</sub>-based sensors detecting VOCs are discussed. Furthermore, the improvement strategies of the SnO<sub>2</sub> sensor from the perspective of nanomaterials are presented. Finally, this paper summarizes the sensing performances of these SnO<sub>2</sub> nanomaterial sensors in VOCs detection, and the future development prospect and challenges is proposed.</p>
