Abstract

The photocatalytic activity of tantalum nitride (Ta₃N ₅) for H₂ evolution under visible-light irradiation (λ > 420 nm) is improved fivefold by 10 MPa ammonia treatment at 823 K. The rate of H₂ evolution of the treated samples is highly related to the treatment time and treatment temperature.
