The surface and near-surface regions of an active catalyst the adjacent gas-phase reactants were investigated simultaneously under reaction conditions using in situ X-ray photoelectron spectroscopy (XPS). This investigation methanol oxidation on a copper showed that there was linear correlation between catalytic activity sample presence subsurface oxygen species can only be observed situ. concentration profile within first few nanometers below determined photon-energy-dependent...

Nanostructured doped ceria is a prospective material for catalytic applications such as the construction of membranes with mixed electronic and ionic conductivity effective syngas production. In this article, surface properties nanostructured praseodymium have been studied by X-ray photoelectron spectroscopy, secondary ion mass spectrometry, Fourier transform infrared spectroscopy adsorbed carbon monoxide.

Contrary to popular opinion, two H atoms from the same H2 molecule can end up in product and retain their spin correlation during heterogeneous hydrogenation on supported metal catalysts thus produce parahydrogen-induced nuclear polarization reaction products (see picture). For 0.6-nm Pt clusters alumina, contribution of pairwise addition route propylene amounts at least 3 %.
We addressed the interaction of oxygen with silver by synchrotron based near ambient pressure X-ray photoelectron spectroscopy at temperatures relevant for industrial oxidation reactions performed catalysts. For single crystals, polycrystalline foils and powders in equilibrium gas phase O(2), we observed dynamics formation five different atomic species relative abundances depending on temperature time. Correlation their kinetics spectroscopic features thermal stability indicates that these...
The method of X-ray photoelectron spectroscopy was used to study the interaction model Pt/TiO2 catalysts with NO2 and following reduction oxidized Pt nanoparticles in vacuum, hydrogen, methane. It shown that, while interacting at room temperature, metal transform, first, into phase which tentatively assigned as particles containing subsurface/dissolved oxygen [Pt-Osub], then, PtO PtO2 oxides. If only first state platinum [Pt-Osub] is formed, it demonstrates exclusively high reactivity toward...

Two oxygen species, which are constituents of the active centers for ethylene epoxidation over silver, have been characterized by a number physical methods sensitive to adsorbate electronic structure such as x-ray photoelectron, ultraviolet Auger, and x-ray-absorption near-edge spectroscopy. One species denoted nucleophilic due its activity in total oxidation only exhibits spectroscopic characteristics close those bulk ${\mathrm{Ag}}_{2}\mathrm{O}.$ This allows us describe this atomically...

Combining first-principles calculations and in situ photoelectron spectroscopy, we show how the composition structure of surface an alloy catalyst is affected by temperature pressure reagents. The Ag-Cu alloy, recently proposed as improved for ethylene epoxidation, forms a thin Cu-O oxide, while found not to be stable. Several possible structures are identified, among which likely dynamically evolve under reaction conditions.
Decomposition and oxidation of methanol on Pt(111) have been examined between 300 650 K in the millibar pressure range using situ ambient-pressure X-ray photoelectron spectroscopy (XPS) temperature-programmed reaction (TPRS). It was found that even presence oxygen, decomposition platinum proceeds through two competitive routes: fast dehydrogenation to CO slow via C–O bond scission. The rate second route is significant range, which leads a blocking surface by carbon prevention further...
