Nanoscale ferroelectric honeycombs, comprised of vertically aligned PbTiO 3 nanotubes, are fabricated by vapor phase reaction between lead acetate‐infiltrated TiO 2 nanotubes and PbO vapor. PbTiO 3 nanohoneycombs converted by vapor phase reaction at 550°C showed well‐aligned nanoscale structure with alignment angle less than 1° and well‐defined ferroelectric properties with the effective piezoelectric coefficient of 44 pm/V. This novel nanoscale structure is expected to facilitate high efficiency sensing of electromechanical and electrochemical stimuli.
