WebThe adsorption of ethene (C2H4)has been studied on Pd (111)and ordered Sn/Pd (111)surface alloys using temperature programmed desorption (TPD),ultraviolet photoelectron spectroscopy (UPS),high-resolution electron energy loss spectroscopy (HREELS),and low energy electron diffraction (LEED).Two surface alloys were prepared … WebThe high-temperature (573 K) adsorption of ethene, propene, propyne, carbon monoxide, and the high temperature co-adsorption of propyne–carbon monoxide have been studied over Pt/alumina and Ni/silica catalysts. The Pt catalyst was found to retain hydrogen from the reduction process, this hydrogen being released by

WebAug 1, 2024 · Heats of adsorption for ethene as a function of coverage at 195 K on H- [Al]ZSM-5 and H- [Fe]ZSM-5 are reported in Fig. 3. The interactions with the Brønsted sites are significantly higher on both samples, with differential heats near 39 ± 2 kJ/mol on both samples at low coverages. The heats also fall to their values on the siliceous sample ... WebMay 14, 2014 · The highest selectivity in adsorption of acetylene relative to that of ethylene was achieved on Au12 (3D) and Au20 (2D) clusters. The interaction of ethylene and acetylene molecules with planar (2D) and nonplanar (3D) gold clusters Aun (n = 10, 12, 20) was studied by the density functional theory (DFT) method. grass valley explosion
