Embedded palladium activation as a facile method for TiO2-nanotube nanoparticle decoration: Cu2O-induced visible-light photoactivity

Abstract

Highly decorated! A direct and efficient way to decorate TiO 2 nanotubes with copper, Cu2O and CuO particles is shown. Active palladium species embedded in the TiO 2 nanotube walls allow specific initiation sites to be triggered for electroless copper deposition. These Cu 2 O- decorated TiO 2 nanotubes could be used for water splitting. © 2013 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
