Surface Nano-Structuring by Adsorption and Chemical Reactions
Nano-structuring of the surface caused by adsorption of molecules or atoms and by the reaction of surface atoms with adsorbed species are reviewed from a chemistry viewpoint. Self-assembly of adsorbed species is markedly influenced by weak mutual interactions and the local strain of the surface induced by the adsorption. Nano-structuring taking place on the surface is well explained by the noti...
متن کاملHydrogen Surface Reactions and Adsorption Studied on Y2O3, YSZ, and ZrO2
The surface reactivity of Y2O3, YSZ, and ZrO2 polycrystalline powder samples toward H2 has been comparatively studied by a pool of complementary experimental techniques, comprising volumetric methods (temperature-programmed volumetric adsorption/oxidation and thermal desorption spectrometry), spectroscopic techniques (in situ electric impedance and in situ Fourier-transform infrared spectroscop...
متن کاملEffects of zeolite structure and aluminum content on thiophene adsorption, desorption, and surface reactions
The adsorption and desorption of thiophene and the reactions of thiophene-derived adsorbed species in He, H2, and O2 were examined on H-ZSM5, H-Beta, and H-Y with varying Si/Al ratios. Thiophene adsorption uptakes (per Al) were independent of Al content, but were above unity and influenced by zeolite structure (1.7, 2.2, and 2.9 on H-ZSM5, H-Beta, and H-Y). These data indicate that thiophene ol...
متن کاملAdsorption and surface reactions of acetaldehyde on TiO2, CeO2 and Al2O3
The adsorption and surface reactions of acetaldehyde at 300–673 K on TiO2, CeO2 and Al2O3 were investigated by Fourier transform infrared spectroscopy and mass spectroscopy. Acetaldehyde adsorbs molecularly in two forms on the surfaces: (i) in a less stable H-bridge bonded form and (ii) in a more stable form adsorbed on Lewis sites through one of the oxygen lone pairs. Both forms of molecularly...
متن کاملAdsorption and reactions at the (0 1 0) V2O5 surface: cluster model studies
The use of quantum chemical approaches in the description of electronic properties of a catalyst and in understanding the mechanism of catalytic reactions is discussed. The electronic structure of vanadium pentoxide, V2O5, is studied based upon the cluster model with ab initio DFT and semiempirical INDO-type methods. Inter-atomic binding in vanadium pentoxide is determined to be of a mixed ioni...
