Photopyroelectric Detection of Hydrogen Oxygen Mixtures
(1993)It has been found that the photopyroelectric (PPE) sensor made of thin-film polyvinylidene fluoride, sputter coated with palladium, can detect trace hydrogen gas in the presence of pure oxygen without significant drift and ...

Photothermal hydrogen sensor: the technique, experimental process, and physicochemical analysis
(2008)The kinetics of hydrogen adsorption and desorption on palladium thin films was studied via photomodulated thermoreflectance measurements. The subsequent analysis based on a Langmuirian isothermal model supports dissociative ...
