In this work, we demonstrate using single particle experiments that hydrogen sorption induces significant grain growth in polycrystalline Pd nanoparticles and that this grain growth constitutes the physical origin of the also observed compensation effect between kinetic parameters. Furthermore, the grain growth considerably slows sorption kinetics, which establishes grain engineering as a new parameter for the design of ultrafast hydrogen sensors.

The imminent large-scale implementation of hydrogen energy technologies requires efficient sensors for hydrogen safety and process monitoring. In our latest work on the topic, we present a teflon-based nanocomposite material that enables the 3D printing of optical hydrogen sensors. Read more here: DOI:10.1021/acsami.1c01968
