Реферат:
The formation of copper oxide cluster structures starting with copper concentrations of 0.5 at % in CuO-ZrO2 catalysts synthesized using ammonium nitrate melts was proved by electronic paramagnetic resonance and diffuse reflectance electron spectroscopy (DRES) measurements. Formations of disperse CuO phase particles appear in samples with copper concentrations above 20 at %. The formation of the volume CuO phase in the CuO-ZrO2 system was observed in samples containing more than 40 at % copper. The DRE spectra were independent of the temperature of calcining, which led us to conclude that copper ions were stabilized in the form of an anomalous solid solution. DRES measurements showed the occurrence of intervalent Cu2+...Cu+ transitions related to the ease of copper ion reduction in oxide cluster structures.
