Structure Of Carbon Monoxide The peaks at 342, 1150, 1523 and 2070 cm −1 correspond to υ(cu c) of η 2 (c, o)–co 2 –, the c=o stretching vibration of υ as (co 2 –), the υ as (co 2 –) of η 2 (c, o)–co 2 and *co of υco at the top position by in situ raman spectra. compared to od cu samples, there were few peaks in the raman spectra and the adsorbed co at the. The 4.25cu cu(al)o x −600, 4.25cu cu(al)o x −700 and 4.25cu cu(al)o x −800 catalysts were obtained through firstly roasting the 4.25cualo x precursor at 600, 700 and 800 °c for 4 h.

Surface lattice oxygen in metal oxides is a common participant in many chemical reactions. given this, the structural design of catalysts to activate lattice oxygen and moreover investigations into the effect of lattice oxygen on reaction pathways are hot topics. with this in mind, herein we prepare cuo–zn1–xcuxo (zco) nanofibers akin to the trojan horse legend and via an in situ reduction. Furthermore, the cu deficient surface structure leads to the formation of cu nano islands on the oxide surface, which was identified as the key feature in stage i. fig. s6 shows a wide interface (∼ 20 nm) between cu 2 o and cu 2−x o with the existence of atomic steps, which are believed to initiate and control the interface reduction [41. The electrochemical co 2 reduction reaction (eco 2 rr) on cu catalysts affords high value added products and is therefore of great practical significance. the outcome and kinetics of eco 2 rr remain insufficient, requiring essentially the optimized structure design for the employed cu catalyst, and also the fine synthesis controls.

To this end, the role of the cu coordination structure is investigated in dictating the activity and selectivity for the co 2 rr and no 3 rr. in agreement with the density functional theory calculations, it is revealed that cu n 4 sites exhibit higher intrinsic activity toward the co 2 rr, whilst both cu n 4 and cu n 4− x c x sites are active. Cuo cu 2 o ncs were prepared via the in situ surface restructuring method during co oxidation with excess o 2 (1 %co air) up to 240 °c for 1 h. agreeing with previous results [42], [45], the morphologies (fig. 1 a2 c2) and xrd patterns (fig. 1 d) of the cuo cu 2 o ncs are similar to those of corresponding cu 2 o ncs, indicating the bulk structure of the cu 2 o ncs does not vary in co.
