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.
