Morphological control of carbon carrier in Pt-carbon nanocomposites derived from photocatalytic reactions on titanium(IV) oxide powders
Abstract
Photodeposition of Pt nanoparticle and phenolic polymer on TiO<sub>2</sub> in a deaerated aqueous system containing hexachloroplatinic acid and phenol were investigated. We observed that reductive deposition of Pt nanoparticles with electrons proceeded rapidly, while the oxidative deposition of a phenolic polymer with positive holes was relatively slow. The difference ensured the encapsulation of Pt nanoparticles between the polymer layer and TiO<sub>2</sub>. Carbonization of the polymer components followed by removing TiO<sub>2</sub> resulted in the formation of two types of Pt-carbon nanocomposites with different morphologies of carbons, depending on photoirradiation duration. These composites exhibited high levels of catalytic activity and reusability for aqueous oxidation of 1-phenylethanol with molecular oxygen.
