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

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
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.
