Аннотация: The size-dependent effects of the heterogeneous reaction PdCl42- + 2e = Pd-0 + 4Cl(-) were studied in hydrochloric acid solutions of H2PdCl4 at 40-70 degrees C. Changes in the structural characteristics of palladium black were analyzed by transmission electron microscopy and X-ray diffraction. The temperature dependence of the redoПоказать полностьюx potential of the PdCl42-/Pd-0 pair was used to determine the thermodynamic characteristics of aggregation of fine-dispersed palladium. The heat effect of the reaction was in satisfactory agreement with direct differential scanning calorimetry measurements.
