Abstract

The distributoin of oxidation states in perovskites of the type LaA1−x B x O3 (A and B transition metal ions) can be “tailored” byx variation. In paticular, in LaNiO3 it has been shown that Fe substitution for Ni foces some Ni3+ into Ni2+, while some Fe3+ changes into the unusual Fe4+ state. In addition, the existence of mixed oxidation states of Fe and/or Ni in LaNi1−x Fe x O3 has been related to its catalytic activity in hydrogen peroxide decomposition. The Fe4+ population, obtained using Mössbauer spectroscopy, was found to be constant for all the analyzed annealing temperatures forx=0.25 concentration, where the isomer shift difference for both states is the highest and the catalytic activity is maximum.
