Abstract

Abstract : A rod-like Ta3 N5 /Ta photoanode was prepared by the reaction of Ta metal plates and NH4 Cl powder in vacuo for photoelectrochemical water oxidation. Abstract : A rod-like Ta3 N5 thin film was synthesized by calcining a vacuum-sealed mixture of Ta metal plates and NH4 Cl powder. Photoelectrochemical water oxidation results showed that an anodic photocurrent of 3.2 mA cm −2 at 1.23 V ( vs. RHE) with a faradaic efficiency of unity for O2 evolution could be achieved by employing the as-prepared Ta3 N5 /Ta as a photoanode.
