Abstract: Focusing on the efficient catalytic degradation of forchlorfenurea (FCF) pollutants, this paper designs an ionic liquid silicon-bismuth photocatalyst (BiSiOClI-IL) prepared from silylated ionic liquids, and develops a comprehensive experiment based on the adsorption and degradation of forchlorfenurea in water by this photocatalyst. The experiment mainly includes the synthesis of the BiSiOClI-IL photocatalyst using silylated ionic liquids, the characterization of the photocatalyst, and the investigation of its catalytic performance. By optimizing the conditions, the optimal preparation parameters were determined as follows: reaction temperature of 80 ℃, a molar ratio of basic bismuth nitrate to silylated ionic liquid to potassium iodide of 3:3:1, and pH 9. The BiSiOClI-IL samples synthesized under different conditions were characterized by various means such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N₂ physisorption. The specific surface area of the photocatalyst reached 21.2 m²·g⁻¹, and the removal rate reached 99% under optimal conditions. Meanwhile, the adsorption mechanism of forchlorfenurea on BiSiOClI-IL was investigated in depth through adsorption kinetic experiments. Integrating knowledge from courses such as physical chemistry, materials chemistry, and instrumental analysis, this comprehensive experiment helps improve students’ experimental skills and cultivate their creative thinking, while providing valuable reference for the removal of organochlorine pollutants.
