Electron paramagnetic resonance (EPR) spectroscopy was applied to study structure-performance relationships for copper-containing catalysts based on Al-Zr-Ce mixed oxides with various oxide support synthesis temperature. In situ EPR showed that the state of Cu 2+ sites depends on the phase composition of the support, temperature, as well as the presence of the reaction medium during catalysis.
