    An exafs study of the influence of the metal particle size, nature of support, and adsorption of H2 and CO on the structure of palladium catalysts (1990)
    Springer
    Catalysis letters 5 (1990), S. 349-352 
    Details
    ISSN: 1572-879X
    Keywords: Palladium ; small particles ; bond distances ; chemisorption

    Topics: Chemistry and Pharmacology
    Notes: Abstract Regardless of the nature of the support (SiO2, C) and the size of the Pd metal particles (19-108 Å), the Pd-Pd interatomic distances are close to those for the bulk metal. Adsorption of CO does not change the structure of the Pd particles, while H2 adsorption at 25 °C leads to an increase of 5–7% in the Pd-Pd distance, evidently as a result of the formation of bulk palladium hydride.

    Synthesis and properties of composite catalysts containing Pd and Ho2O3 particles in pores of carbon carrier (1991)

    Description / Table of Contents: Abstract Катализаторы, полученные через стадию взаимодействия C3H5PdC5H5 с поверхностью вакуумированного Ho2O3/C, обладают на два порядка большей по сравнению с Pd/C удельной активностью как в синтезе CH3OH, так и CH4. Из данных по дезактивации сделано предположение об образовании CH3OH и CH4 на разных активхых центрах.
    Notes: Abstract Specific activity (TOF) of the catalysts prepared through the interaction of C3H5PdC5H5 with the surface of evacuated Ho2O3/C is two orders of magnitude higher compared to that of Pd/C in the synthesis of both CH3OH and CH4. Deactivation data suggest that CH3OH and CH4 are formed on different active sites.

    Composite Pd/Pr4O7/C catalysts: Synthesis, dispersity and properties (1996)
    Springer
    Reaction kinetics and catalysis letters 59 (1996), S. 179-185 
    Details
    ISSN: 1588-2837
    Keywords: Palladium on carbon ; methanol synthesis ; Pr4O7 promoter
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The catalysts prepared sequentiallyvia the interaction of C3H5PdC5H5 with the surface of evacuated Pr4O7/C and reduction with H2 at 573 K, contain 20–30 Å Pd particles and Pr4O7 particles〈20 Å. The catalysts obtained have two-order of magnitude higher specific activity in the CH3OH synthesis than Pd/C.

    Description / Table of Contents: Abstract Катализаторы, приготовленные взаимодействием C3H5PdC5H5 с поверхностью вакуумированного Ho2O3/C, после восстановления H2 при 573 К содержат частицы Pd размером 30 Å и частицы Ho2O3 размером 20–40 Å. Согласно данным XPS и TEM частицы Pd являются электроположительными, а их поверхность частично покрыта оксидом Ho.
    Notes: Abstract Catalysts prepared through the interaction of C3H5PdC5H5 with the surface of evacuated Ho2O3/C after reduction by H2 at 573 K contain Pd and Ho2O3 particles whose size is 30 and 20–40 Å, respectively. XPS and TEM data indicate that Pd particles have a positive charge and their surface is partly covered by Ho oxide.
