Using cu(111) as a reference, the ultimate o to cu ratio for cu(211) corresponds to (0.030 0.069) × 0.5 ml = 0.22 ml o cu, i.e., approximately cu 4 o. however, based on the rairs signals of postadsorbed co, we expect the oxygen saturated surface to be closer to stoichiometric cu 2 o. this is discussed in full in the supporting information.

(fig. 10 b) when the immersion duration was extended, the reduction degree of go on the cu foil gradually increased.

One of the main reasons for the strong resistance of a flat surface to oxidation is that, when cu atoms are oxidized, the out of plane distance between cu layers increases from 2.10 to 2.48 Å. The xps survey clearly shows that the main element for each cu–n–c t material is c, n, o, and cu (fig. 5 a). the high resolution cu 2p spectra for all samples consisted of two main peaks, which are located at 932.3 ev (cu 2p3 2) and 952.6 ev (2p1 2), respectively, indicating the metallic cu 0 chemical state (fig. 5 b) [51], [53].

The cu–o 4 sites in cu dbc with low reaction energy barrier show better ecr performance compared to those nitrogen coordinated cu sites. the design of proposed conductive mof may establish.
