A novel MIL 53 (Al-Fe)@SiO₂ was formulated and employed to treat organic dye containing effluent by an integrated method of adsorption followed by photocatalytic degradation. The MIL 53 (Al-Fe)@SiO₂ was synthesized using coal fly ash. The in-depth characterizations of the newly synthesized material enlighten the phenomenal changes in the physical and chemical properties of MIL 53 (Al-Fe)@SiO₂ than that of raw fly ash, which enhances its adsorption capacity in three folds. Moreover, the PL spectroscopy analysis depicts that the newly produced MIL 53 (Al-Fe)@SiO₂ has slower electron-hole recombination than that of MIL 53 (Al) and MIL 53 (Al)@SiO₂. The MIL 53 (Al-Fe)@SiO₂ offered a maximum adsorption capacity of 681.782 mg g⁻¹ and maximum 89.34 and 99.95 % degradation in the presence of visible and UV light radiations, respectively. This study shows that the proposed MIL 53 (Al-Fe)@SiO₂, outperforms the conventional materials in treating the industrial effluents for harmful pollutants.

配制了一种新型的MIL 53（Al-Fe）@SiO ₂，并通过集成的吸附方法随后进行光催化降解来处理含有机染料的废水。MIL 53（Al-Fe）@SiO ₂是使用粉煤灰合成的。新合成材料的深入表征启发了MIL 53（Al-Fe）@SiO ₂的物理和化学性质比原始粉煤灰的显着变化，从而将其吸附能力提高了三倍。此外，PL光谱分析表明，新产生的MIL 53（Al-Fe）@SiO _2的电子-空穴复合速度比MIL 53（Al）和MIL 53（Al）@SiO _2的电子-空穴复合慢。MIL 53（铝铁）@SiO ₂在可见光和紫外光辐射的存在下，其最大吸附容量分别为681.782 mg g ^-1和最大89.34和99.95％的降解。这项研究表明，拟议的MIL 53（Al-Fe）@SiO ₂在处理工业废水中的有害污染物方面优于传统材料。
