Functionalization of TiO₂ and Janus-TiO₂ Nanoparticles with Organosilanes for Tunable Pickering Emulsification and Photocatalytic Wastewater Treatment.

ABSTRACT: This study examines the use of organosilanes to functionalize titanium dioxide (TiO₂) and Janus-TiO₂ nanoparticles, enabling precise control of surface chemistry for stabilizing Pickering emulsions. Organosilanes with varying hydrophobic chain lengths3-aminopropyltrimethoxysilane (APS), octyltrichlorosilane (OTS), and trichloro-(octadecyl)-silane (ODTS)were employed to modify TiO₂ surfaces, creating nanoparticles with tailored wettability. Comprehensive characterization, including contact angle measurements, FT-IR, TGA, and zeta potential analysis, confirmed successful modification and demonstrated the correlation between nanoparticle surface properties and emulsification efficiency. APS-functionalized particles exhibited enhanced emulsion stability, achi
