Fig. 4

TEM images of (a) Cu2O cube, b Cu2O aggregate, c cCu, and (d) their XRD patterns after CO2RR in the H-type cell. TEM images of (e) Cu2O cube, f Cu2O aggregate, g cCu, and (h) their XRD patterns after CO2RR in the MEA cell for 10 min at 3 V. i–l Images show the same analyses after an additional 120 min at 3.5 V in the MEA cell.
