Title
Three-dimensional plasmonic Ag/TiO2 nanocomposite architectures onflexible substrates for visible-light photocatalytic activity
Description
This work was supported by the Center for Advanced Meta-Materials (CAMM)funded by the Ministry of Science, ICT and Future Planning as GlobalFrontier Project (CAMM-No. 2014M3A6B3063707), and Human ResourcesProgram in Energy Technology of the Korea Institute of Energy TechnologyEvalua-tion and Planning (KETEP), granted financial resource from theMinistry of Trade, Industry & Energy, Republic of Korea (No.20164010201000).
abstract
In this study, a periodic three-dimensional (3D) Ag/TiO2 nanocomposite architecture of nanowires was fabricated on a flexible substrate to enhance the plasmonic photocatalytic activity of the composite. Layer-by-layer nanofabrication based on nanoimprint lithography, vertical e-beam evaporation, nanotransfer, and nanowelding was applied in a new method to create different 3D Ag/TiO2 nanocomposite architectures. The fabricated samples were characterized by scanning electron microscopy, transmission electron microscopy, focused ion-beam imaging, X-ray photoelectron spectrometry, and UV-visible spectroscopy. The experiment indicated that the 3D nanocomposite architectures could effectively enhance photocatalytic activity in the degradation of methylene blue solution under visible light irradiation. We believe that our method is efficient and stable, which could be applied to various fields, including photocatalysis, solar energy conversion, and biotechnology.
