Unveiling the synergistic role of anatase/brookite homojunctions in TiO2 mixed phases on the enhanced photocatalytic degradation of paracetamol under simulated solar light and the formation of CO2.− radical ion

Applied Surface Science Advances
Mixed-phase TiO₂ systems offer unique opportunities for enhancing photocatalytic performance via interpolymorph junctions (homojunctions). While anatase/rutile interfaces have been extensively studied, anatase/brookite junctions remain comparatively ...

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

ChemElectroChem, 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
