Insights Into the Mechanistic Assessment of Plasmon‐Induced Aqueous Degradation of Pharmaceuticals by TiO2/Ag Nano‐Composite

Water and Environment Journal, EarlyView.
ABSTRACT Pharmaceutical contaminants in potable water sources are ubiquitous and have resulted in lowered water quality. Thus, two common broad‐spectrum pharmaceuticals (tetracycline‐TC and ciprofloxacin‐CPF) were comparatively photo‐degraded using Ag‐doped TiO2 photocatalyst species containing Ag nanoparticles at 2.5, 5, and 7.5 wt%.

Effect of Yttrium Doping on Titanium Dioxide

Journal 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

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

Mechanistic Insights into the High Selectivity and Photocatalytic Activity of Brookite TiO2 toward NOX Abatement

, 2023
TiO2 nanomaterials are promising photocatalysts for NOx depollution from air under sunlight irradiation. It commonly exists in three phases, i.e., anatase, rutile, and brookite. Anatase, rutile, and a mixture of them are heavily studied.

Calcination‐Induced Pore Evolution in TiO2 Supports Governing Ni Accessibility for Dry Methane Reforming

ChemistryOpen, Volume 15, Issue 5, May 2026.
Ni/TiO2 catalysts with tunable pore structures were developed to study how support calcination temperature affects Ni accessibility and dry reforming of methane (DRM, CH4 + CO2 → syngas). Low‐temperature TiO2 forms mesopores that trap Ni, while high‐temperature calcination generates macroporous/plate‐like structures that expose Ni and enhance catalytic

Strain and grain size of TiO2 nanoparticles from TEM, Raman spectroscopy and XRD: The revisiting of the Williamson-Hall plot method

Results in Physics, 2018
The Williamson-Hall (W-H) equation, which has been used to obtain relative crystallite sizes and strains between samples since 1962, is revisited. A modified W-H equation is derived which takes into account the Scherrer equation, first published in 1918,
