Engineering MXene-, LDH-, and MOF-Based NO2 Sensors for Sustainable Environmental Monitoring: Mechanisms, Performance, and Practical Challenges
Nitrogen dioxide (NO2) is one of the hazardous air pollutants, and its sensitive detection requires sensors that combine low-temperature operation with high selectivity, recovery, humidity tolerance, and long-term stability. This review critically evaluates MXene-, layered double hydroxide (LDH)-, and metal–organic f...
