FeOOH and Fe2O3 co-grafted TiO2 photocatalysts for bisphenol A degradation in water

Abstract Novel FeOOH and Fe 2 O 3 co-grafted TiO 2 photocatalysts were synthesized and tested for bisphenol A (BPA) degradation in water under simulated solar and visible light irradiations. The grafting temperature was simply controlled to adjust the FeOOH and Fe 2 O 3 compositions, with 55 °C being the optimal temperature that led to the highest BPA degradation. Co-grafted FeOOH and Fe 2 O 3 on TiO 2 is advantageous over mono-grafted or un-grafted TiO 2 , because FeOOH promotes BPA adsorption and Fe 2 O 3 enhances photocatalytic activity by facilitating the interfacial charge transfer. Findings from this study contribute to the fabrication of efficient, low-cost photocatalysts for water pollutant removal.
