Palladium-based catalysts are abundantly utilised in catalytic selective hydrogenation reactions of unsaturated hydrocarbons, such as alkynes and diolefins1,2 and are considered as fundamental components, both in the industrial and academic field3.

The current work in the frame of the CATLAB project focuses on the development of novel catalysts based on thin-film technology. This study aims to investigate Pd-based thin-film catalysts on various substrates used in hydrogenation of acetylene by means of advanced scanning/transmission electron microscopy (S/TEM) in terms of morphology, structure and elemental composition.

Catalysts and reference materials were produced by the Helmholtz-Zentrum Berlin (HZB) using sputtering deposition.
