Fig. 2: Structures of CuL/Cu2O.

From: Low-coordinated copper facilitates the *CH2CO affinity at enhanced rectifying interface of Cu/Cu2O for efficient CO2-to-multicarbon alcohols conversion

Fig. 2

A XRD pattern, B HRTEM image, and C corresponding elemental mapping of CuL/Cu2O showing the interface between Cu and Cu2O domains. D The Tauc plots (αℏν)2 versus light energy (ℏv) derived by transforming the Kubelka–Munk function on the basis of the inserted UV–vis diffuse absorption spectrum, where Eg is energy bandgap. E The surface potential of CuL/Cu2O and corresponding variation of surface potential along with the orientation of the white line, where the gray arrows are the difference between the vertical coordinates corresponding to the two dashed lines and the darker color means lower surface potential. F Work function determined by UPS measurements. G Electrostatic potential, H 3D electron density difference distributions with yellow indicating charge density accumulation and blue indicating deplete and I 2D display of electron localization function of CuL/Cu2O: red displays high electron density and blue is low.
