Facile ion-exchanged synthesis of Sn2+ incorporated potassium titanate nanoribbons and their visible-light-responded photocatalytic activity

Reprint of “Photocatalytic reduction of CO2 on MgO/TiO2 nanotube films”

“…3. Moreover, we also found that the layer spacing of the nanotubes decreased to 0.550 nm, this may be due to the shrink of TAN in the processing of high-temperature calcination [30]. Observation on the TEM images of MgO modified TiO 2 , we found that the nanotubular structure was kept very well.…”

Rapid template-free synthesis and photocatalytic performance of visible light-activated SnNb2O6nanosheets

“…These results reveal that the chemical state of Sn on the sample is Sn 2+ . 39 It further demonstrates that oxidation to Sn 4+ from Sn 2+ is efficiently prevented by this synthesis method. By observation of the Nb 3d spectrum (Fig.…”

Tin(II) Antimonates with Adjustable Compositions: Effects of Band‐Gaps and Nanostructures on Visible‐Light‐Driven Photocatalytic H2 Evolution

“…This result was consistent with the EDS analysis and confirmed the high purity of the chemical compositions. In the high‐resolution XPS spectra of the Sn 3d orbitals for all of the SnSb‐ Tt samples, the Sn 3d 5/2 and Sn 3d 3/2 peaks were detected at around 486.7 and 495.1 eV (Figure 2), respectively, and were ascribed to the Sn 2+ cations 7f,g,i,l. Furthermore, the two Sn 3d peaks showed neither a double‐peak structure nor strong asymmetry, thereby excluding the existence of Sn in other valence states, such as Sn 4+ 15.…”
