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.
