Hydrogen mobility in activated MoS2 catalysts
The layered crystal molybdenum disulfide, MoS2, is one of the most studied candidate catalyst for replacing the rare and expensive platinum in hydrogen. Its activity can be enhanced considerably by the creation of active sites via plasma treatment. Despite intense recent research efforts, there is a lack of understanding how hydrogen moves and reacts in the activated catalysts. This is important, because two alternative reaction mechanisms have been proposed for water electrolysis at MoS2 surfaces, which differ in the step of recombination to molecular hydrogen. Here, we propose to use QENS and spin-echo spectroscopy to study hydrogen diffusion in untreated and plasma-treated MoS2 samples. In using well-defined powder samples we will be able to extract the diffusion of hydrogen in this important catalyst material with unprecedented precision.
