Broadband visible‐light harvesting over TiO 2 is achieved by introducing gold nanorods (Au NRs) as antennas based on localized surface plasmon resonance. Furthermore, surfactant removal is achieved by an HClO 4 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.
