The standard electrode potentials for the formation of the pure solid and molten compounds Li2ZrCl6, Li2HfCl6, Na2ZrCl6, Na2HfCl6, K2ZrCl6, K2HfCl6, Cs2ZrCl6, and Cs2HfCl6 have been calculated from measured vapour pressures corresponding to their thermal decomposition at equilibrium and from available thermochemical data. Reversible potentials for the formation of Na2ZrCl6 and of K2ZrCl6 in solution according to the reaction[Formula: see text]where A is Na or K, have been calculated from available equilibrium vapour pressures as functions of the mole fractions of the alkali hexachlorocompounds. Standard potentials for the above reaction and "formal" potentials are also given. The latter are useful in predicting the electrochemical behaviour of dilute solutions of the hexachlorozirconates in alkali metal chlorides.


It has been shown by Evans (1937) that the effects of the alkali metal chlorides at a hexane-water interface are markedly similar to the effects of the same salts on the surface tension of water as determined by Heydweiller (1910) and Schwenker (1931), i.e. the tension apparently increases steadily with concentration. Hence, from the Gibbs adsorption principle, the salt is negatively adsorbed throughout. The recent work of Jones and Ray (1937) has, however, demonstrated that the surface tension of the salt solutions examined by them first decreases with increase of concentration, passes through a minimum and subsequently increases beyond the value possessed by pure water. On general grounds it would be expected that phenomena similar to those observed by Jones and Ray at the free surface should likewise be exhibited at an interface. In an attempt to investigate this point interfacial tension data have been obtained for the interface dekalin ( trans -decahydro- naphthalene)/water, using salts of various valence type.

In the present study, Ni-Pd/Al2O3 catalyst supported on α-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation of the foam with ultrasonically aerosolized salt solutions at 473 K and drying at that temperature. Calcination step was excluded and the catalyst was reduced at very low temperature – 533 K. The reforming experiment lasted for 3 h, with standing time of 1 h at the following temperatures: 873, 973 and 1023 K. Conclusions on selectivity, catalytic activity and stability were reached on the basis of CO and H2 yields.
