Metal-doped niobate pyrochlores and double-perovskites for glycerol valorization: structural and electronic properties and DFT calculations

“…41,42 Besides, these vibrations are located in a similar position to those of the Cu 3 Nb 2 O 8 phase, as found earlier. 31,32 For ZnNb, two sets of vibrations constituting 23 Raman modes are detected, all of them in agreement with literature reports on the orthorhombic zinc niobate ZnNb 2 O 6 (D 14 2h ) crystal structures reported. 33,43 Moreover, Raman bands of the Zn 3 Nb 2 O 8 phase are located in positions close to that of ZnNb 2 O 6 , 35,36 which corroborates with the XRD results.…”

“…This result is also corroborated by the Rietveld refinement, which suggested the presence of the aforesaid phase, and is in good agreement with the findings. 31,32…”

“…This result is also corroborated by the Rietveld refinement, which suggested the presence of the aforesaid phase, and is in good agreement with the findings. 31,32 The diffraction peaks representing the orthorhombic ZnNb 2 O 6 pyrochlore phase (ICSD 36290) for ZnNb is found. Besides, the columbite-type orthorhombic structure belongs to the space group Pbcn and possesses lattice constants a = 14.208 Å, b = 5.726 Å, and c = 5.04 Å and lattice angles α = β = γ = 90°, in line with the findings.…”
