Role of different coordinated Cu and reactive oxygen species on the highly active Cu–Ce–Zr mixed oxides in NH₃-SCO: a combined in situ EPR and O₂-TPD approach

Abstract

Novel Cu–Ce–Zr mixed oxides were synthesized by a citric acid sol–gel method, and they exhibited an excellent NH₃-SCO activity (180 °C, TOF = 1.33 h⁻¹).
