Remarkably, as interlayer for LiS batteries, the TiO-TiO2 heterostructure not only enhances the adsorbability of the interlayer to lithium polysulfides (LiPSs) via the Lewis acid-base interactions, but also accelerates the redox reaction kinetics of the LiS batteries dramatically. Moreover, the BN...
Lu3+ ion has an ion radius of 0.086 nm, which, according to the Hume-Rothery rule [15], could be a suitable acceptor to obtain the EPDD-based co-doped TiO2 ceramics. Moreover, so far, there are no reports on the dielectric properties of (Nb5+, Lu3+) co-doped TiO2 ceramics. ...
(Nb5 , Si4 ) co-doped TiO2 (NSTO) ceramics with the compositions (Nb0.5Si0.5)xTi1xO2, x = 0, 0.025, 0.050 and 0.1 were prepared with a solid-state reaction technique. X-ray diffraction (XRD) patterns and Raman spectra confirmed that the tetragonal rutile is the main phase in all ...

TiO2 thin film was prepared at the element molar ratio 1.0∶1.5∶10 of tin,zinc and titanium,with the pH value 2.Compared with pure TiO2,co-doped TiO2 had 85nm red shift and declined its band gap.Under the circumtance that SnO2 and ZnO have no effect on TiO2 structure,XRD and SEM ...
Gd–La codoped TiO2 nanoparticles with diameter of 10 nm were successfully synthesized via a sol–gel method. The photocatalytic activity of the Gd–La codoped TiO2 nanoparticles evaluated by photodegrading methyl orange was significantly enhanced compared to that of undoped or Gd or La mono-doped...
