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.
