Novel FeOOH and Fe2O3 co-grafted TiO2 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 Fe2O3 compositions, with 55 °C being the optimal temperature that led to the highest BPA degradation. Co-grafted FeOOH and Fe2O3 on TiO2 is advantageous over mono-grafted or un-grafted TiO2, because FeOOH promotes BPA adsorption and Fe2O3 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.
