Abstract

Black TiO₂ is of great interest for efficient solar harvest in photocatalytic and photoelectrochemical applications. In this work, we report a convenient, low-cost, and safe method for producing black TiO₂ nanotube arrays (TNTAs). By a simple soaking in an ethylene glycol (EG) solution of NH₄F, the as-anodic TNTAs turn black, with a substantial amount of oxygen vacancies and Ti³⁺ sites induced. The thus-obtained black TNTAs deliver greatly enhanced photoelectrochemical and photocatalytic performance of high stability.
