Abstract

The scope of the electron paramagnetic resonance (EPR) technique in catalysis is often limited because of the presence of the ferromagnetic nanoparticles in many catalytic systems. The present work gives an effective method to discriminate solid-state EPR spectra in the microwave resonance absorption while investigating such systems. The approach is based on the different features of the EPR spectra and ferromagnetic resonance absorption that are simultaneously observed in the system.

Notes

  1. It is necessary to keep in mind that discussions about the statistical formation process of the unaveraged spectrum leave open the question about the physical nature of the individual lines.
