“…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.…”

The modified Pechini method has been applied to the preparation of nano-structured SnO 2 and SnO 2 :CuO. The sample characterization was carried out by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), infrared spectroscopy (IR) and nitrogen adsorption isotherms (BET). The CuO phase in SnO 2 :CuO samples was successfully characterized by XRD, XPS and IR. The highest degree of crystallinity and subsequently the maximum intensity and area of CuO (002) diffraction peaks were observed for the samples prepared with templates. The morphology and microstructure of the hybrid were studied using SEM. The core level binding energies of Cu 2p, Sn 3d, and O 1s were measured in these samples. The appearance of a satellite peak in the Cu 2p spectra provided definitive evidence for the presence of Cu 2? ions in these samples. The influence of synthesis conditions such as solvent, precursor type, calcinations temperature and time on the detectability of CuO and the morphology and microstructure of the hybrid were also studied. The calcinations conditions had a significant effect on the appearance and intensity of CuO diffraction peaks.

“…When 2.5% Sb 2 O 3 or CeO 2 was added to SnO 2 , solid solutions were formed, while in the case of In 2 O 3 addition in the same amount, a mixture of phases was obtained [29]. In the case of SnO 2 -CuSb 2 O 6 pseudobinary system, a limited solid solubility for the end members of the system was established [30].…”

“…That could be a confirmation of the inclusion of the CuSb 2 O 6 compound in the rutile type structure as a Cu 1/3 Sb 2/3 O 6/3 moiety [Mihaiu et al, 2001]. The CuSb 2 O 6 based solid solutions were lesser studied [Mihaiu et al, 2001;Scarlat et al, 2002]. It is known that CuSb 2 O 6 compound crystallizes in a distorted monoclinic trirutile structure in space group P2 1/c or P2 1/n [2] with folllowing unit cell parameters: a=4.6324Å, b=4.6359 Å, c=9.2967 Å and °=91.12.…”

“…In the case of the sample which contains the highest quantity of CuSb 2 O 6 incorporated in the SnO 2 matrix, the magnetic susceptibility (χ g,293K ) value of 2.5 × 10 -6 cm 3 /g is very close to those obtained in the case of mixture of phases (χ g,293K =2.9× 10 -6 cm 3 /g). That could be a confirmation of the inclusion of the CuSb 2 O 6 compound in the rutile type structure as a Cu 1/3 Sb 2/3 O 6/3 moiety [Mihaiu et al, 2001]. The CuSb 2 O 6 based solid solutions were lesser studied [Mihaiu et al, 2001;Scarlat et al, 2002].…”
