Sustainable Approach for Spent V2O5–WO3/TiO2 Catalysts Management: Selective Recovery of Heavy Metal Vanadium and Production of Value-Added WO3–TiO2 Photocatalysts

“…21–1272), respectively. The PL spectrum is an important tool for the analysis of the separation efficiency of electron–hole pairs in TiO 2 photocatalysts Figure b demonstrates that both the as-regenerated WO 3 –TiO 2 and the P25 photocatalysts exhibit PL peaks in the range of 350–550 nm with an excitation at 325 nm.…”

“…The PL spectrum is an important tool for the analysis of the separation efficiency of electron−hole pairs in TiO 2 photocatalysts. 32 Figure 7b demonstrates that both the asregenerated WO 3 −TiO 2 and the P25 photocatalysts exhibit PL peaks in the range of 350−550 nm with an excitation at 325 nm. By comparing the curves of as-regenerated WO 3 −TiO 2 and P25 photocatalysts, we observe that the intensity of the peaks decreases in the order P25 > as-regenerated WO 3 −TiO 2 photocatalysts.…”

Investigation of Some Characterizations of Black TiO\(_2\) Nanotubes Via Spectroscopic Methods

“…The obtained peaks of both the pristine TNAs and the black TNAs are almost similar to each other about the Raman shift values. The Raman scattering peaks in the range of 120 cm −1 to 700 cm −1 could be assigned to the stretching modes of Ti-O bonding in TiO 2 crystal [12]. For the TNAs and the black TNAs, the typical peaks have been obtained at the same wavenumber of 380 cm −1 , 505 cm −1 , and 631.2 cm −1 corresponding to the typical anatase Raman bands of B 1g , A 1g , and E g vibration modes, respectively [13].…”
