Facile synthesis of submicron Cu2O and CuO crystallites from a solid metallorganic molecular precursor

Soft-template assisted synthesis of mesoporous CuO/Cu 2 O composite hollow microspheres as efficient visible-light photocatalyst

“…2B) [17,18]. Moreover, the spectra of these samples display several strong satellite peaks between Cu 2p 3/2 peak and its first satellite on the higher enery side of about 8 eV, which is the characteristic of the material such as CuO having a d 9 configuration in ground state [19,20] (Fig. S2C-S2D), further confirming that the well-defined CuO/Cu 2 O composite hollow microspheres can only be obtained when the MR is 10.…”

Characterization of CuO phase in SnO2–CuO prepared by the modified Pechini method

“…For comparison, IR spectra for pure CuO, pure SnO 2 and a mechanical mixture of the two powders containing 7 w/w % of CuO are also shown. For pure SnO 2 and CuO all relevant IR bands were found to lie within the reported spectral ranges [31][32][33][34][35][36]. The IR spectrum of the mechanical mixture is a sum of the IR spectra of the components.…”

Controlled growth of CuO/Cu2O hollow microsphere composites as efficient visible-light-active photocatalysts

“…3A), four peaks corresponding to the Cu 2p 3/2 (933.5 and 935.3 eV) and Cu 2p 1/2 (953.5 and 955.4 eV) are observed. According to the literature [27], the peaks at 933.5 and 953.5 eV are the characteristic peaks of Cu 2 O, while that at 935.3 and 955.4 eV are attributed to the CuO, suggesting the formation of Cu 2 O and CuO composite. However, only peaks at 933.5 and 953.5 eV can be observed from Cu 2p spectrum of the sample prepared at other pH values (taking the sample prepared with pH 6.5 as an example), indicating the formation of pure Cu 2 O.…”
