Effect of Yttrium Doping on Titanium Dioxide

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT The wide band gap and chemical–mechanical stability of titanium dioxide (TiO2) make it one of the most important semiconductor materials for photocatalytic applications. However, its performance is limited by its low absorption in the visible light region. In this study, yttrium (Y)‐doped TiO2 (Y/TiO2) powders containing 1%, 5%, and 10% Y were

Deepening on the Intercalation Pseudocapacitive Behavior of Ti0.33Nb0.66O2 Rutile as the Anode Material for Lithium‐Ion Batteries

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
This study shows that the beneficial effect of Nb by Ti partial substitution on TiO2 consists of a significant increase in the lithium diffusion coefficient, resulting from the opening of structural tunnels. This explains the intercalation pseudocapacitive behavior of Nb‐derivatives of TiO2. The electrochemical performance of a rutile with high niobium
