Spectroscopic evidence for origins of size and support effects on selectivity of Cu nanoparticle dehydrogenation catalysts

|
By M. E. Witzke, P. J. Dietrich, K. Al-Bardan
| Chemistry World Verified
Selective dehydrogenation catalysts that produce acetaldehyde from bio-derived ethanol can increase the efficiency of subsequent processes such as C–C coupling over metal oxides to produce 1-butanol or 1,3-butadiene or oxidation to acetic acid. Here, we use in situ X-ray absorption spectroscopy and steady state kinetics experiments to identify Cu at the perimeter of supported Cu clusters as the active site for esterification and Cu surface sites as sites for dehydrogenation.
