a In-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) of Mn2O3/SmMn2O5 (Mn2O3/SMO) and SmMn2O5 (SMO) under NO + O2 at 200 °C. Time-resolved in-situ DRIFTS spectra of the (b) SMO and (c) Mn2O3/SMO under NO gas at 200 °C. d Time-resolved isotopic 36O2 exchange reaction at 300 °C, (e) time-resolved isotopic 36O2 labeled online MS for CO oxidation at 150 °C, (f) time-resolved isotopic 36O2 labeled online MS for NO oxidation at 300 °C.
