title: Light wavelength-switchable photocatalytic reaction by gold nanoparticle-loaded titanium(IV) dioxide.
abstract: Surface plasmon resonance excitation of gold nanoparticle-loaded on titanium(IV) dioxide (Au/TiO(2)) by visible light (lambda > 420 nm) has led to selective oxidation of thiol to disulfide, whereas the reaction is reversed by UV light irradiation (lambda > 300 nm).
