Ultra-selective and stable ethylene detection <i>via</i> exsolution of catalytic Ni nanoparticles in chemiresistive gas sensors
We developed a Ni–ZnO sensor for sub-ppm ethylene detection with enhanced selectivity, humidity resistance, and thermal stability. These properties were achieved by exsolving catalytic Ni nanoparticles on the surface of ZnO support sensing layers.
