The adsorption of dihydrogen on gold nanoparticles is observed by a shift in the surface plasmon resonance of gold, during argon/hydrogen cycles. This is induced by the dissociation of the H2 molecules and negative charge transfer from Au to Au–H bondings.

Solution processed TiO2 anatase film was used as sensitive layer for H2 detection for two plasmonic sensor configurations: A grating-coupled surface plasmon resonance sensor and a localized surface plasmon resonance sensor with gold nanoparticles. The main purpose of this paper is to elucidate the different H2 response observed for the two types of sensors which can be explained considering the hydrogen dissociation taking place on TiO2 at high temperature and the photocatalytic activity of the gold nanoparticles.
