A high-performance room-temperature NO2 gas sensor based on MoS2/MoOx multiphase heterojunction: Achieving fast response and low detection limit

Key Points

• Achieving a low detection limit enhances the sensor's applicability in environmental monitoring—providing reliable air quality assessments.
• The heterojunction of MoS2 and MoOx optimizes electronic properties, leading to a significant improvement in response time of the sensor.
• Response times were notably fast, allowing for near-instantaneous detection of nitrogen dioxide levels in ambient air conditions.
• Further development could lead to widespread use in various industries focused on air quality and pollution monitoring.
