Visible Light Response of ZrO2 by Nitriding and its Photocatalytic Activity
A novel Zr2ON2 catalyst was successfully prepared by nitriding ZrO2, which has a potential enough for H2 formation by the reduction of water under UV irradiation. It was found that the Zr2ON2 had a stable photocatalytic activity for water oxidation and reduction in the presence of sacrificial reagents (methanol or Ag+) under visible light irradiation (λ < 500 nm).
