Abstract
Efficient detection methods are needed to monitor nitrogen dioxide (NO2), a major NOx pollutant from fossil fuel combustion that poses significant threats to both ecology and human health. Current NO2 detection technologies face limitations in stability and selectivity. Here, we present a transition metal nitride sensor that exhibits exceptional selectivity for NO2, demonstrating a sensitivity 30 times greater than that of the strongest interfering gas, NO. The sensor maintains stability over 6 months and does not utilize platinum or other precious metals. This notable performance has been achieved through preparation of highly active titanium nitride (TiNx) nanoparticles with exceptionally large surface area…
