Gold‐Nanorod‐Photosensitized Titanium Dioxide with Wide‐Range Visible‐Light Harvesting Based on Localized Surface Plasmon Resonance

Abstract

Broadband visible-light harvesting over TiO2 is achieved by introducing gold nanorods (Au NRs) as antennas based on localized surface plasmon resonance. Furthermore, surfactant removal is achieved by an HClO4 oxidative method. Not only transversal but also longitudinal plasma of Au NRs can induce photooxidation of 2-propanol, which extends the light harvesting to the near-infrared region. Scale bar: 10 nm.
