Vapor growth of binary and ternary phosphorus-based semiconductors into TiO2 nanotube arrays and application in visible light driven water splitting

Polyphosphide–TiO₂ hybrid materials, like SnIP@TiO₂, are used as photocatalysts for PEC-water-oxidation: SnIP a double helix semiconductor reacted as nanofibers onto and into TiO₂ nanotube arrays. Due to synergetic effects an enhanced water splitting performance was found.
