2014, Applied Catalysis A: GeneralCitation Excerpt :For SiO2, γ-Al2O3 and SiO2-Al2O3 supported Ru catalysts, the shift of the reduction peak to higher temperature should be ascribed to the strong metal–support interaction (SMSI) [31]. Indeed, it is reported that the SMSI is the reason of the increased reduction temperature of the ruthenium species on Al2O3 [31]. Several literatures have demonstrated that Ru species is present in two chemical states (metallic and oxidized state) on the Ru/γ-Al2O3 catalyst, confirmed by X-ray photoelectron spectroscopy (XPS) and/or CO-FTIR techniques [20,22,31–33].

2011, Applied Surface ScienceCitation Excerpt :X-ray photoelectron spectroscopy was used to characterize the electronic state of ruthenium on the acidic and basic supports in order to identify the reason for the observed differences in catalytic behavior of Ru/EOx systems [7,8,12–17]. The experimentally determined binding energy (BE) of the Ru 3d5/2 core level was ranged between 279.5 and 280.0 eV for ruthenium supported on MgO or CaO [7,8,12], but between 280.2 and 280.6 eV for ruthenium supported on Al2O3 or SiO2 [13–17]. For comparison, the reported BE(Ru 3d5/2) values for bulk Ru metal vary from 279.9 to 280.2 eV depending on the instrument calibration [18].
Aqueous-phase hydrodeoxygenation of carboxylic acids to alcohols or alkanes over supported Ru catalysts
2011, Journal of Molecular Catalysis A: ChemicalCitation Excerpt :For all catalysts, the maximal reduction temperature increases in the following order: Ru/C < Ru/ZrO2 < Ru/Al2O3, indicating that the support material greatly influences the reducibility of the Ru species. Indeed, the strong metal–support interaction (SMSI) is the reason of the increased reduction temperature of the ruthenium species on Al2O3 compared with ZrO2 [45]. Asakura and Iwasawa [46] have reported that the Ru species on Al2O3 have strong chemical interaction between metal and support through the Ru–O–Al bonding by extended X-ray absorption fine-structure (EXAFS) analysis.
