In situ real-time neutron imaging of gaseous H₂ adsorption and D₂ exchange on carbon-supported Pd catalysts

We use in situ neutron imaging to observe the adsorption/absorption of hydrogen within a packed catalyst bed of a Pd/C catalyst at a spatial and temporal resolution of similar to 430 mu m and a similar to 9 s respectively. Additionally, the H-2/D-2 exchange process across the catalyst bed is followed in real time.
