A Catalytic-Plasmonic Pt Nanoparticle Sensor for Hydrogen Detection in High-Humidity Environments.

ABSTRACT: The detection of hydrogen gas in humid air environments is a key unresolved challenge for hydrogen safety in the rapidly growing hydrogen energy technologies, which hold a key to abate the CO₂ emissions from particularly challenging sectors that together represent more than 20% of man-made CO₂. In this work, we introduce a catalytic-plasmonic optical hydrogen sensor that employs nanofabricated and plasmonically active Pt nanoparticles as transducer elements for hydrogen detection in highly humid environments in air. Leveraging the combination of the Pt nanoparticles' intrinsic high activity in the catalytic hydrogen oxidation reaction with their high sensitivity in plasmonic dielectric sensing, we show that this catalytic-plasmonic sensor is able to operate in the ent
