Mixing it up! N 2p states of N‐doped TiO 2 nanotubes become predominant near the Fermi level, which is a discrete energy level at the top edge of a valence band, whereas it deteriorates the good hybridization between Ti 3d and O 2p. This leads to a reduced band gap for selective atomic N‐doped nanotubes and gives enhanced photovoltaic performance (see graphic).
