摘要：

Adsorption measurements, x-ray diffraction analysis, magnetic static and resonance methods, and electronic spectroscopy were used to study the structure of Ni/TiO2 catalysts obtained by the reduction of a jointly precipitated highly dispersed oxide system. The TiO2 surface retains its high value in catalysts containing 4.2-28.6 wt % Ni and reduced at 250-500°C. Highly dispersed nickel crystals are not stabilized on this surface. The reasons for this effect are discussed.
