On Dehydrogenation Catalyser

Dehydrogenation of Benzene on Liquid

The reactions of benzene on Al100 + have been investigated as a function of cluster temperature (300−1100 K) and relative kinetic energy (1−14 eV) by low-energy ion-beam methods and mass spectrometry. Benzene chemisorbs on both solid and liquid aluminum clusters to generate Al100C6D6 . A series of Al100−n + (n = 1, 2, 3, ...) products was also observed. As the cluster temperature was raised abo...

Step enhanced dehydrogenation of ethanol on Rh

We have investigated the adsorption and decomposition of ethanol on the Rh(111) and Rh(553) surfaces at room temperature with special emphasis on the dehydrogenation. We use high resolution core level photoemission and density functional theory (DFT) based simulations. A detailed analysis of the C1s core level spectra, including analysis of the vibrational fine-structure and comparison to calcu...

Dehydrogenation by Heterogeneous Catalysts

Pyridine Hydrogenation and Piperidine Dehydrogenation

The dehydrogenation of piperidine has been studied and found to have an order of -1.5 with respect to the hydrogen partial pressure. By combining these results with those obtained for pyridine hydrogenation on the same catalyst a complete rate equation for piperidine dehydrogenation together with the stoichiometric number of the rate-determining step of these reactions could be derived. This nu...

Toward Low-Temperature Dehydrogenation Catalysis: Isophorone Adsorbed on Pd(111).

Adsorbate geometry and reaction dynamics play essential roles in catalytic processes at surfaces. Here we present a theoretical and experimental study for a model functional organic/metal interface: isophorone (C9H14O) adsorbed on the Pd(111) surface. Density functional theory calculations with the Perdew-Burke-Ernzerhoff (PBE) functional including van der Waals (vdW) interactions, in combinati...
