title = "Hydrogen Sensors from Composites of Ultra-small Bimetallic Nanoparticles and Porous Ion-Exchange Polymers",
abstract = "We have developed the facile and versatile synthesis of ultra-small bimetallic nanoparticles (NPs) using porous ion-exchange polymers. PdPt NPs derived from porous ion-exchange polymers show superior hydrogen (H2)-sensing performances at room temperature in air, with an ultra-low detection limit (0.4 ppm). The synergistic effect of PdPt NPs on H2 sensing is demonstrated through experimental results and simulations. In addition, a wireless H2-sensing system is achieved by combining our synthesis method with radio-frequency communication.",
