“…The distances between the lattice fringes is ca. 0.26 and 0.22 nm, corresponding to the d-spacing of the (111) and (200) plane of the monoclinic CuO crystal [36], which is consistent with the XRD results. As described above, the hierarchical Cu@CuO linear heterostructure can be facilely synthesized by the spontaneous oxidization route.…”

“…S5a (see Supporting Information). The results indicate that Cu (II) oxidation state is the only species, not other copper states in the ternary hybrid sample [36,40]. It means that the linear Cu core might be oxidized in the high temperature condition during the hydrothermal process.…”

“…To date, TiO 2 and ZnO have been the most extensively investigated semiconductor photocatalysts due to their unique blend of properties, and have demonstrated excellent photocatalytic activity towards complete degradation of wide range of organic dyes. As an important p-type semiconductor metal oxide with a narrow band gap (1.2-1.5 eV), copper oxide (CuO) has drawn increasing research attention due to its attractive properties like nontoxicity, excellent reactivity, chemical stability, electrochemical activity, low production cost and abundant availability, and has been widely used in diverse applications like gas sensors, solar cells, field emissions, Li-batteries, supercapacitors, and catalysis [4][5][6][7][8][9]. Unfortunately, the reports on the photodegradation of organic dyes using CuO as photocatalyst is limited as the activity of pure CuO is not high enough due to the fast recombination of photogenerated electron-hole pairs [10][11][12][13][14][15][16].…”

“…The existence of shake-up satellite peak (944.2 eV) on the higher binding energy side is a typical characteristic of CuO, which rules out the possibility of the presence of Cu 2 O phase[35]. The Zn 2p core level XPS spectra(Fig.…”
