Abstract

Surfactant free "bare" palladium nano-rosettes and polymer hybrid palladium nanospheres have been fabricated using dynamic thin films associated with a spinning disc processor. We have demonstrated the effectiveness of using the high surface area to volume ratio Palladium nano-rosettes in real time hydrogen sensing which shows a fast response time down to 0.1% (by volume). More interestingly, we have demonstrated for the first time that the dissociative adsorption of hydrogen in the hybrid palladium nanospheres induces a Mott insulator to metal transition. This finding represents a new paradigm in hydrogen sensing.
