Dopamine‐Modified Trititanate Nanotubes with UV‐ and Visible‐Light Photocatalytic Activity: Coordinative Self‐Assembly into a Recyclable Absorber

Abstract The search for a simple method to bestow trititanate nanotubes with visible‐light activity for applications as solar‐driven photocatalysts remains a challenging task. Here, we report that self‐assembled surface modification by dopamine imparted trititanate nanotubes (TiNT) with stable, recyclable photocatalytic activity under UV and visible‐light illumination. The controlled surface modification shifted the absorption onset into the visible region. These dopamine‐modified trititanate nanotubes are expected to have applications in water treatment and in pollutant degradation.
