Ag nanoparticles-TiO2 film hybrid for plasmon-exciton co-driven surface catalytic reactions
Source abstract
Abstract
Abstract In this paper, different sizes of Ag nanoparticles grown on TiO 2 film have been fabricated using UV-photoreduction method and studied by UV–vis absorption spectroscopy, ultrafast transient absorption spectroscopy and surface-enhanced Raman scattering (SERS) spectroscopy. The results demonstrated that the plasmon-exciton coupling degree can be well manipulated by changing Ag nanoparticle size, because the surface plasmon resonance (SPR) peak can be controlled by Ag nanoparticle size. The strongest plasmon-exciton coupling occurred when the SPR peak of Ag nanoparticles superposed with the absorption peak of exciton of TiO 2 film, which is the optimal catalytic platform for surface catalytic reactions. Our findings might promote a deeper understanding of the reaction mechanism for plasmon-exciton co-driven surface catalytic reactions.
