Fig. 1: Design scheme and structural characterizations.

From: Stabilized Cu0 -Cu1+ dual sites in a cyanamide framework for selective CO2 electroreduction to ethylene

Fig. 1

a Schematic illustration of the construction of Cu0-Cu1+ catalytic sites: (i) Electrochemical induction. (ii) Heterojunction interface. (iii) Stabilized Cu0-Cu1+ dual sites via cyanamide framework (this work). b XRD patterns of Cuδ+NCN, CuNCN and CuO. c SEM and (d) TEM images of Cuδ+NCN. e FFT diagrams of of Cuδ+NCN. f Aberration-corrected HAABF-STEM images of Cuδ+NCN along the [001] zone. g EDS mapping of Cuδ+NCN.
