Abstract

Abstract:

The TiO₂-supported Ag nanoparticles were prepared by hydrolytic polycondensation of titanium tetrabutoxide with salicylaldimine Schiff base functional monomer. The prepared Ag/TiO₂ nanocatalysts were characterized by FTIR, XRD, HRTEM and UV-Vis, and tested for CO oxidation. The particle size of Ag nanoparticles and the structure of TiO₂ supports can be controlled by the content of functional monomer and calcined temperature, and therefore, the catalytic activity of Ag/TiO₂ nanocatalysts can be controlled. The maximum conversion of CO reached 99.9% for the sample with 20% of the functional monomer and calcined at 873 K.

Key words: Schiff base, titanium dioxide, silver, nanoparticle, oxidation
