Synergistic Enhancement Effect of Palladium-Silver Alloy Nanoparticle Catalysts Towards High-Sensitive Hydrogen Detection

摘要

. To form a PdAg enhanced ZnO chemiresistive sensor, ZnO nanowires array is firstly grown onto an integrated MEMS chip and then, PdAg NPs are homogeneously self-assembled onto the surface of ZnO nanowires via an ultrasonic method. Our sensor exhibits highly sensitive to ppm-level H
