Abstract

Platinum particles were photochemically deposited on TiO₂ by using poly(vinyl alcohol) (PVA) as an electron donor and a protecting polymer. TEM and EXAFS studies showed that diameter of Pt particles prepared in H ₂O solution with PVA was smaller than that prepared in H ₂O/ethanol mixture with or without PVA, and the Pt particles had each particle diameter between 1.0 and 2.0 nm and good dispersity of particles on TiO₂. The Pt/TiO₂ catalyst prepared in H₂O solution with PVA showed the highest activity for CO photooxidation, and the order of the activity was the same as that of the Pt particle size.
