摘要：

The acid-base and adsorption properties of the active sites of the surface of a skeletal nickel and promoted nickel catalyst in aqueous solutions were studied by the potentiometric and pK spectroscopy methods. Titanium added as a promoter resulted in an increased number of lines in the pK spectra, which may attest to higher chemical activity of the promoted catalyst. An increase in the pH value of the media was shown to cause a shift in the process equilibria toward the formation of atomic strongly-bound forms of adsorbed hydrogen.
