Fig. 5: Structure sensitivity of Cu2O catalysts and DEP process studies.

(a) EIS spectra (using a 1 M KOH electrolyte dissolved in deionized water), (b) O2-TPD patterns and (c) XPS patterns of O of s-Cu2O, s-Cu2O-NC and s-Cu2O-NF. In situ DRIFTS spectra after exposing s-Cu2O-NF to the flow of C3H6 and mixed flow of C3H6, O2 and N2 (10: 5: 85 vol.%) at (d) 150 °C and (e) 250 °C.
