Abstract

We report a facile method to produce active photocatalysts by treating niobium oxyhydroxide/TiO₂ composites with H₂O₂. The peroxo-niobium groups generated on the oxyhydroxide make the composite active under visible light. The interaction between the niobium oxyhydroxide and TiO₂ enhanced the photogenerated charge separation on the composite, and consequently its photocatalytic activity.
