Query: Graphitic C3N4 Sensitized TiO2 Nanotube Layers: A Visible Light
  Activated Efficient Antimicrobial Platform   In this work, we introduce a facile procedure to graft a thin graphitic C3N4
(g-C3N4) layer on aligned TiO2 nanotube arrays (TiNT) by one-step chemical
vapor deposition (CVD) approach. This provides a platform to enhance the
visible-light response of TiO2 nanotubes for antimicrobial applications. The
formed g- C3N4/TiNT binary nanocomposite exhibits excellent bactericidal
efficiency against E. coli as a visiblelight activated antibacterial coating.
