Abstract

Pt/TiO₂ catalysts were prepared by a colloidal deposition method including the photochemical preparation of Pt nanoparticles protected by poly(N-vinyl-2-pyrrolidone) and their deposition by liquid-phase adsorption on TiO₂. Pt/TiO₂ catalysts prepared by the colloidal deposition method with oxidation and H₂ reduction treatment showed higher CO oxidation activity than those obtained by impregnation and photodeposition techniques. FTIR studies revealed the reactivity of CO species adsorbed on Pt sites of these catalysts. The higher activity was ascribable to higher dispersion and higher reactivity of CO adsorbed on Pt particles. Graphical Abstract: [Figure not available: see fulltext.]
