Abstract:Nitrogen dioxide (NO 2 ) is a significant environmental and human health hazard. Current NO 2 sensors often lack sensitivity and selectivity under ambient conditions. This study investigates ammonia pyrolysis modification of monolayer Ti 3 C 2 T x MXene to enhance NO 2 detection at room temperature. Nitrogen-doped Ti 3 C 2 T x demonstrates a substantial improvement in sensitivity, with a response of 8.87% to 50 ppm of NO 2 compared to 0.65% for the original sensor, representing a 13.8-fold increase. The nitrog… Show more
