Hydrogen sensing capabilities of highly nanoporous black gold films
Original language description
Hydrogen sensing is a crucial topic regarding the green deal and the use of hydrogen as a next-generation energy source/energy-storage medium. Chemiresistive nanostructured materials can provide a large surface area for hydrogen adsorption. We present a detailed study of the hydrogen sensing capabilities of highly nanoporous black gold films that show fast response and recovery times (0.5 min) while operating at low temperatures (40◦ C). The films with different levels of nanoporosity were prepared and tested to a hydrogen concentration in the range of 0.25–0.95 %. Film properties were characterized by AFM, SEM, XPS and Variable Energy Positron Annihilation Spectroscopy. We found that nanoporous black gold is suitable as an active layer of chemiresistor for hydrogen sensing and that its sensitivity is the function of the film nanoporosity. Possible mechanisms of hydrogen-gold interactions are discussed.
