Fund Project: This work was supported by the National Natural Science Foundation of China (21506156, 51661145026, 21676193), the Tianjin Municipal Natural Science Foundation (15JCZDJC37300, 16JCQNJC05200), and the Pakistan Science Foundation (PSF/257NSFC-Eng/P-UoL (02)).

Adsorption and photodegradation are promising approaches for removing organic pollutions. In this study, we combined these two processes by co-loading Fe-TiO₂ and Fe₂O₃ quantum dots (QDs) on porous MCM-41, using a simple hydrolysis method. X-ray diffraction, high-resolution transmission electron microscopy, and X-ray photoelectron spectroscopy results indicated that Fe-TiO₂ QDs are formed at low Fe precursor concentrations, while additional Fe₂O₃ QDs are formed at higher Fe precursor concentrations. The Fe₂O₃ and Fe-TiO₂ QDs impart high adsorption capacity and high photoactivity to the porous MCM-41, respectively. Thus, their combination results in a synergic effect of the adsorption and photodegradation. The highest-performing sample exhibits excellent performance in removing rose bengal from aqueous solution.
