Researchers develop concept for ultra-fast hydrogen sensor; plasmonic metal–polymer hybrid nanomaterial

Green Car Congress

In a paper in the journal Nature Materials , the team presents a plasmonic metal–polymer hybrid nanomaterial concept, in which the polymer coating reduces the apparent activation energy for hydrogen transport into and out of the plasmonic nanoparticles, while deactivation resistance is provided via a tailored tandem polymer membrane.
