Corrigendum: Chemical Activity of Thin Oxide Layers: Strong Interactions with the Support Yield a New Thin‐Film Phase of ZnO

Abstract

It has been pointed out to the authors that there is at ypographical error in the theoretical part of the experimental section of the original Communication. Specifically, the metal supercell used in the theoretical calculations was 5 5i nstead of the published 4 4. The resulting simulation cell was thus a4 4(bi-)layer of ZnO on 2 layers of 5 5C u(111). As also later pointed out by Bieniek et al.[1] this yields alattice mismatch between the two materials of only ca. 1% in order to strain the resulting ZnO overlayer structure as little as possible. The structures given in the abstract picture, Figure 3and the coordinates in the Supporting Information show the correct 4 4ZnO @5 5Custructure.

The Cu–Al2O3 interface: an unignorable active site for methanol steam reforming hydrogen production

“…3b, two obvious infrared bands at 2098-2100 cm −1 and 2114-2115 cm −1 were observed and assigned to the linear adsorption of CO on Cu 0 and Cu + , respectively. 35,36 The CO adsorption on 2.5Cu/Al 2 O 3 produced a broad and symmetrical infrared band with a wavenumber (2111 cm −1 ) between Cu 0 and Cu + . Hence, the CO adsorption over 2.5Cu/Al 2 O 3 should be assigned to the Cu δ+ species, Catalysis Science & Technology Paper…”

Gas-Dependent Active Sites on Cu/ZnO Clusters for CH3OH Synthesis

“…The upshift of the vibrational frequencies of CO stretching from 2091 to 2098 cm −1 and then to 2116 cm −1 (Figure 3g) together with the gradually enhanced signal at 2184 cm −1 (assigned as CO* on O*/ Cu(111), Section S2.4 and Table S3) suggests an increase in O* coverages on Cu/ZnO clusters with increasing CO 2 -to-CO ratios. 26,27 The intensity of the CO stretching band on Cu sites increased continually with the increasing ratio, indicating an increase in Cu surface sites. The intensity of the CO stretching band on Zn−Cu sites increased to a maximum value and then decreased with further increasing the CO 2 -to-CO ratio, which matches the trends of the atomic fraction of surface Zn (or Zn 2+ ) versus the ratio.…”
