Abstract
Photocathodic protection has emerged as an eco-friendly and energy-saving technology for alleviating the corrosion of underwater metallic infrastructures. In a photocathodic protection system built from single-domain ferroelectric PbTiO3 nanoplates, the aligned depolarization fields of individual nanoplates provide a “highway” for the photogenerated charges so that the electrons are guided to unidirectionally flow to the protected metal. The cover image (DOI: 10.1002/elt2.51) depicts the schematic diagram of the well-aligned depolarization fields of the PbTiO3 nanoplates, the induced directional transport “highway” of electrons and holes, and the photogenerated electrons traveling to metallic structures (such as bridges and ships) for anti-corrosion purposes.
