1519. HURST, W. W. AND RIDEAL, E. K. Promoting Action of Palladium on Copper. I. Catalytic Combustion. Jour. Chem. Soc., vol. 125, 1924, pp. 685-694; Chem. Abs., vol. 18, 1924, p. 1775.
Ratio CO : H2 burned in a mixture of the gases containing O2 at the surface of Cu, and Cu containing, admixed with it, varying quantities of Pd has been measured. A real specific promoting effect was observed and the addition of Pd to Cu definitely increased the ratio CO : H2. The promoting action of Pd on Cu is ascribed to a peculiarity of the Cu-Pd interface. The anamalous activities of molecules at interfacial boundaries and points of discontinuity are cited in favor of this view.
