Size Effects of TiO2 Nanoparticles as Supports for W‐ and NiW‐Catalysts for Selective 3‐Methylthiophene Desulfurization

open access: yesChemCatChem, EarlyView.
Rounded TiO2 nanoparticles we sucesfully synthesized with modulated sizes from 109 to 22 nm. We observed the WS2 and NiWS active phases forming parallel slabs to the surface. The presence of Ni helped W to be better dispersed, especially on the smallest nanoparticles, which resulted in the highest activity detected among the series.

Thermally Assisted Photocatalytic Hydrogen Production Using TiO₂/Cu: Evaluation of Performance and Stability

open access: yesChemCatChem, EarlyView.
Thermal enhancement of TiO2/Cu photocatalysis boosts H2 production from 3,847 µmol g−1 h−1 at 40°C to 10,421 µmol g−1 h−1 at 70 °C. Elevated temperatures improve charge separation and reaction kinetics while maintaining catalyst stability. The synergistic photothermal approach demonstrates Cu/TiO2 as an efficient, noble‐metal‐free system for ...
