Abstract
Titanium dioxide containing a few percent of ruthenium has been investigated by electron spin resonance and X-ray diffraction. Prolonged treatment in hydrogen at temperatures < 350 °C or the addition of NbV to the rutile structure leads to the formation of the paramagnetic RuIII in solid solution. Upon increasing the temperature of the hydrogen treatment, the reduction is continued to RuII in solid solution and finally to Ru0 as a segregated phase.Keywords
