Abstract

Stania-supported palladium shows a strong synergistic effect in catalysing carbon monoxide oxidation: measurements in the temperature range 20–160°C showed that the reactant inhibition effect and the activation energy of this catalyst are significantly lower than those of silica- and alumina-supported palladium. The rate curve is monotonic under stoichiometric conditions whereas it exhibits a local maximum in excess of oxygen. These features are accounted for by a model that incorporates spillover of carbon monoxide from the metal to the support and its subsequent reaction there. The support accelerates the rate by reducing the coverage of the metal by carbon monoxide.

Atomically dispersed gold-supported catalysts: preparation and potential for low-temperature CO oxidation
2018, Materials Today Nano
Citation Excerpt :
Sheintuch et al. prepared series of Pd/SiO2 catalysts by loading Pd on silica (SiO2) for the first time [16]. Schryer et al. supported Pt on SiO2 to obtain Pt/SiO2 catalyst [17]. After the loading, the dispersibility of Pd and Pt is excellent, and the overflow of CO and O2 exists on the carrier.
The development of carbon monoxide (CO) oxidation catalysts with excellent activity and high stability is of great significance for both theoretical research and practical application. Supported Au nanocatalysts have been displayed to have extremely high catalytic activity for CO oxidation reactions. However, Au has limited reserves resulting in high cost. It is necessary to increase the utilization efficiency of Au while obtain high activity. In addition, the stability of Au is poor because Au tends to migrate and aggregate to the larger particles, which have low catalytic activity, during long-term use, especially when used in elevated temperature. The key issues concern how to stabilize the Au particles. Moreover, the reaction mechanism of CO oxidation on these catalysts is not clear. In this mini-review, we discussed atomic-dispersed Au-supported catalysts and their high activity and stability by the strong interaction between Au and supports in recent years, and their catalytic mechanisms were further elucidated.
Structure dependence and reaction mechanism of CO oxidation: A model study on macroporous CeO<inf>2</inf> and CeO<inf>2</inf>-ZrO<inf>2</inf> catalysts
2016, Journal of Catalysis

Currently, the interaction between CO and CeO2 during the reaction has emerged as one of the most important issues to understand the catalytic mechanism. The reaction models include rapid adsorption of CO molecules on low-coordination surface noble metal sites and its subsequent oxidation at the perimeter of metal nano-particles where oxygen is activated [19–21]. For the independent ceria based catalysts, CO oxidation is believed to proceed via Mars-van Krevelen mechanism over ceria [22–24].
Three-dimensionally ordered macroporous (3DOM) CeO₂ and CeO₂-ZrO₂ oxides with different particle sizes, oxygen vacancy concentrations, oxygen mobility and preferentially exposed surface planes were synthesized, which, as model catalysts, give a new approach for understanding the structural dependence and reaction mechanism of CO oxidation over CeO₂-based catalysts. The prepared 3DOM CeO₂ and CeO₂-ZrO₂ catalysts exhibited much higher catalytic activity for CO oxidation than the nonporous samples. Although the textural and reducible features of catalysts could affect the catalytic performance, the preferentially exposed surface plane is crucial for determining the catalytic activity. The {1 1 0} plane of CeO₂ could create more active sites for CO adsorption, resulting in relatively high activity for CO oxidation. Higher concentration of oxygen vacancy would also enhance the reactivity for CO oxidation. Langmuir-Hinshelwood mechanism should be the crucial reaction pathway for CO oxidation over the 3DOM CeO₂-based catalysts, although the Mars-van Krevelen mechanism cannot be ignored.
Low temperature CO oxidation over Pd catalysts supported on highly ordered mesoporous metal oxides
2012, Catalysis Today

Fernández-García et al. [18] and Zhu et al. [19] found that Pd/CeO2, Pd/TiO2, and Pd/CeO2–TiO2 catalytic activities can be improved by pre-reduction, and especially by low temperature reduction pretreatment, because it enhances metal–support interactions and oxygen vacancy formation. Also, strong synergistic effects between Pd metal and oxide support have been observed for Pd/SnO2 catalysts, during CO oxidation [1,20]. Recently, mesoporous materials have been regard to many technical applications.
Highly ordered mesoporous metal oxides (meso-MO_x) such as CeO₂, Co₃O₄, Mn₂O₃, SnO₂, and TiO₂ were successfully synthesized by using nano-replication method, and Pd-loaded meso-MO_x (Pd/meso-MO_x) catalysts for CO oxidation were investigated. The catalysts were characterized by X-ray diffraction, N₂ adsorption–desorption, electron microscopy, CO-temperature programmed desorption (CO-TPD), and H₂-temperature programmed reduction (H₂-TPR). All of the catalysts exhibited highly ordered mesostructure and a high surface area (>100 m² g⁻¹). The Pd-loading on meso-MO_x supports enhanced catalytic activities compared with those of MO_x supports only. Among the catalysts, Pd/meso-Co₃O₄ showed a high catalytic activity. The activities of Pd/meso-Co₃O₄ and Pd/meso-Mn₂O₃ were only slightly increased compared to the corresponding meso-MO_x materials, whereas Pd/meso-CeO₂, Pd/meso-SnO₂ and Pd/meso-TiO₂ exhibited significant increases in the catalytic activities. XPS spectra showed that Pd species had strong interactions with meso-CeO₂, meso-SnO₂ and meso-TiO₂, and less interaction with meso-Co₃O₄ and meso-Mn₂O₃. These results suggest a synergistic effect between metal and the supports and the catalytic behaviours and activities are highly dependent on the nature of supports. The catalytic activities of Pd/meso-MO_x can be further improved by a pre-reduction treatment. After H₂ pretreatment, all of the catalytic activities were increased. Especially, the Pd/meso-CeO₂ exhibited highest activity after the H₂ pretreatment. Because the pretreatment enhances metal–support interaction and the formation of oxygen vacancies and hydroxyl groups around Pd or the surface interaction phase, which is participated by influencing electronic state of the surface active sites.
The electro-oxidation of carbon monoxide, hydrogen/carbon monoxide and methanol in acid medium on Pt-Sn catalysts for low-temperature fuel cells: A comparative review of the effect of Pt-Sn structural characteristics

Bond et al. [23] proposed a bifunctional mechanism based on the spillover of both carbon monoxide and oxygen from the noble metal to tin dioxide. Sheintuch et al. [24] also consider a bifunctional mechanism but restrict the spillover to CO. Schryer et al. [25] ascribed the activity enhancement for CO oxidation to the presence of a PtSn alloy.
The electrocatalytic activity for CO, H₂/CO and CH₃OH oxidation of Pt-Sn catalysts has been extensively investigated for a possible use as anode materials for low-temperature fuel cells. This paper presents an overview of the relationship between the structural characteristics of the catalysts (catalyst composition, degree of alloying, presence of oxides) and their electrocatalytic activity for the oxidation of the different fuels.
Photoelectron-spectroscopic and reactivity investigation of thin Pd-Sn films prepared by magnetron sputtering
2007, Applied Surface Science
We have studied Pd–Sn layers with different composition prepared by magnetron sputtering. Layers were sputtered onto Al₂O₃ and SiO₂ substrates and studied by X-ray photoelectron spectroscopy (XPS). Spectra confirmed that after vacuum annealing residual oxygen and carbon have been removed and bimetallic bonds have been created. The shift of Pd 3d_5/2 core level to higher binding energy followed by the peak narrowing in dependence on the composition was observed, accompanied by the shift of the Pd 4d in the valence band region, induced by hybridization of Pd-d and Sn-s,p states. Experiments carried out on a gas-flow reactor indicate increasing temperature of the CO oxidation with tin ratio in the alloy.
Photocatalytic microbial inactivation over Pd doped SnO<inf>2</inf> and TiO<inf>2</inf> thin films
2006, Journal of Photochemistry and Photobiology A: Chemistry
The photocatalytic antimicrobial activity over TiO₂, SnO₂ and their Pd doped thin film samples were determined against Escherichia coli, Staphylococcus aereus, Saccharomyces cerevisiae and Aspergilus niger spores. Higher antimicrobial activity was observed with TiO₂ than SnO₂ thin films and, Pd addition contributes to an increase in the activity of both semiconductor oxides. The highest microbial inactivation was achieved with 1% PdO/TiO₂ against E. coli with a 98% decrease in survival after 2 h illumination. SnO₂ was found to show lower photocatalytic efficiency against E. coli with a 56% decrease in survival after 2 h illumination and a 68% decrease in survival of E. coli after palladium addition. E. coli showed the least and S. cerevisiae showed the highest resistance against photocatalytic inactivation and, A. niger spores could not be inactivated up to 8 h illumination over all the surfaces. The antimicrobial efficiencies against different microorganisms and fungal spores were found to decrease in the following order: E. coli > S. aereus > S. cerevisiae > A. niger spores for which, complexity and strength of the cell walls increased in the same order.
