“…4) shifted lower after adsorbed toluene, especially fit adsorbed toluene in the 90%N 2 + 10%O 2 . This could be attributed to the existence of FeSi or FeSi 2 (Li et al, 2015). This indicated that the toluene adsorption could increase the interaction between Fe and supporter, which benefitted the performance of catalyst activity.…”

The adsorption of volatile organic compounds (VOCs) and O 2 on the surface of the catalyst was one of the vital progresses in the plasma-catalytic oxidation of VOCs. In this work the breakthrough curves of toluene adsorption on the 3%FeO x /SBA-15 were measured under the various O 2 concentrations. The results showed that the breakthrough time of toluene reduced with increasing O 2 . Competitive adsorption was observed on the catalyst surface between O 2 and toluene. The catalysts adsorbed the toluene under the various O 2 concentrations were characterized by O 2 temperature-programmed desorption (O 2 -TPD), and X-ray photoelectron spectroscopy (XPS). The desorption amounts of O 2 -and the Fe percentage on the catalyst surface were dependent on the O 2 concentration during toluene adsorption. The experimental results of pure SBA-15 and 5%MnO x /SBA-15 indicated the competitive adsorption site of O 2 and toluene was FeO x . In situ FTIR data of toluene adsorption on the catalyst surface indicated that the adsorption state of toluene could not be impacted by the competitive adsorption of O 2 , and the O 2 adsorbed on the catalyst could oxidize toluene.

“…As an example, we note ion beam assisted physical or chemical deposition coatings and thin films for improving both adhesion behaviour and physicochemical properties [1][2][3][4]. Low-energy inert-gas ion beam is often used in the various methods of surface analysis of semiconductors and metals, for example, in secondary ion mass spectrometry (SIMS) [5,6] and transmission electron microscopy (TEM) [7,8].…”

It is well known that the metal-surface properties vary because of the ion sputtering of surface layers in a vacuum. This review contains results of the studies of kinetics change of both oxygen adsorption and oxidation on the surface of transition metals and alloys in a vacuum during the lowenergy ( 10 keV) Ar + ions' bombardment. Particularly, the results of the systematic studies of a surface of the Cu, Ni, Fe, Co single crystals, and Fe-Ni alloy are presented. The important role of such parameters as a dose of the ion bombarding, ion energy and sample temperature in the chemical activity of a surface is noted. As argued, mechanism of interaction in surface-gas system is substantially controlled by the optimal ratio between the energy and the primary ion current density as well as the sputtering rate of natural oxide on the target surface.Добре відомо, що властивості поверхні металу змінюються в результаті йонного розпорошення поверхневих шарів у вакуумі. Даний огляд міс-тить результати досліджень зміни кінетики адсорбції кисню й окис-нення на поверхні перехідних металів і стопів у вакуумі при бомбарду-ванні йонами Ar + низької енергії ( 10 кеВ). Зокрема, наведено резуль-тати систематичних досліджень поверхні монокристалів Cu, Ni, Fe, Co та стопу Fe-Ni. Зазначено важливу роль таких параметрів як доза бом-бардування, енергія йонів і температура зразка у зміні хемічної актив-ности поверхні. Наведено докази того, що механізм взаємодії в системі газ-поверхня істотно контролюється оптимальним співвідношенням між енергією та густиною первинного йонного струму, а також швидкі-стю розпорошення природного оксиду на поверхні мішені. 210 M.
