Isothermal decomposition of γ-irradiated palladium acetate

Abstract

The isothermal decomposition of un-irradiated (pristine) and pre-γ -irradiated palladium acetate was studied in the temperature range (498-508 K) and in air using the isothermal thermogravimetric technique. The data were analysed using various solid state reaction models. The results showed that the kinetics of isothermal decomposition of palladium acetate was governed by random nucleation reaction (Erofe'ev equation A 3 ). The activation energies of the main decomposition process for un-irradiated and pre-γ -irradiated samples were calculated. The change in texture and crystal structure of the investigated palladium acetate by γ -irradiation was studied using electron microscopy and X-ray diffraction techniques.

Effect of support conductivity of catalytic powder on electrocatalytic hydrogenation of phenol

“…A corresponding exothermic phenomenon was attributed to the formation of reduced metal Pd particles. The same observation was reported by Mahfouz et al [20]. Rella et al [21] attributed this phenomenon to the spontaneous reduction of Pd to form nano-sized metal clusters.…”
