Fabrication of Cu2O-loaded TiO2 nanotubes with heterojunctions via an electrochemical method: enhanced photocatalytic activity

Modified TiO 2 nanotubes (NTs) have been widely used in water splitting for hydrogen evolution owing to their excellent photocatalytic properties. Here, Cu 2 O nanoparticle-decorated TiO 2 NTs were fabricated via electrochemical deposition, and its performance was investigated.
