Visible-light-driven photocatalytic behavior of tantalum-oxynitride and nitride

Visible-light-driven photocatalytic behavior of tantalum-oxynitride and nitride Tantalum oxynitride (TaON) and tantalum nitride (Ta3N5) are investigated in detail as visible-light-responsive photocatalysts. It is found that TaON and Ta3N5 evolve H2 or O2 via bandgap excitation in the presence of a sacrificial electron donor or acceptor, respectively. These materials exhibit high stability against photo-corrosion under the reaction conditions for H2 and O2 evolution. Structural and physical properties of these photocatalysts were also investigated in detail. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Tantalum oxynitride (TaON) and tantalum nitride (Ta3N5) are investigated in detail as visible-light-responsive photocatalysts. It is found that TaON and Ta3N5 evolve H2 or O2 via bandgap excitation in the presence of a sacrificial electron donor or acceptor, respectively. These materials exhibit high stability against photo-corrosion under the reaction conditions for H2 and O2 evolution. Structural and physical properties of these photocatalysts were also investigated in detail.
