TiO2-doped with selenium showed greater visible absorption and exhibited superior photocatalytic activity than undoped TiO2. The prepared catalyst was subjected to reflux in Millipore water in order to remove the surface-bound selenium species. After this treatment, the catalyst did not show any leaching and showed efficient recycling with consistent catalytic efficiency.
