Peroxo-niobium oxyhydroxide sensitized TiO2 crystals†
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.
