Abstract

Phosphorus-doped TiO₂ nanotube arrays have been prepared via a phosphine annealing protocol and have been found to be efficient towards visible-light-driven water oxidation. Optimal visible light photocurrents of 0.25 mA cm⁻² at 1.23 V and 0.85 mA cm⁻² at 2.0 V vs. the RHE are achieved, which are the best reported values for phosphorus-doped TiO₂.
