采用原位聚合法制备了氯氧化铋(BiOCl)与聚苯胺(PANI)复合的Ⅱ型异质结光催化剂BiOCl/PANI，并采用X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)、紫外可见漫反射光谱(UV-Vis DRS)和N2吸附-脱附测试等多种技术手段对其进行了表征，考察了BiOCl/PANI在模拟可见光下对罗丹明B (RhB)的光催化降解性能。实验结果表明：BiOCl/PANI催化剂比PANI和BiOCl具有更高的光催化活性，在RhB质量浓度为50 mg·L^-1、PANI与BiOCl的物质的量之比为0.02∶1、50 mg·L^-1的催化剂条件下，所制备的BiOCl/PANI光催化150 min后，RhB降解率为98.8%，速率常数为0.031 min^-1；经过4次循环实验后，RhB降解率从98.8%降低至98.4%，表现出良好的稳定性和可重复利用性。光催化剂BiOCl/PANI实现了电子和空穴对的快速分离，降低了二者在催化剂内部的复合速率，提高了光催化性能。

仪器分析实验“分子荧光法测定罗丹明B的含量”存在实验过于简单、未考虑实际情况等问题。因此，本改进实验在三维荧光扫描模式下获取样本数据，不进行复杂预处理，而是运用化学计量学算法解析出目标分析物的纯信号，进而实现了染色辣椒中罗丹明6G和123的同时测定。本改进实验提高了学生全面考虑问题和创新解决问题的能力。

A simple two-step hydrothermal method synthesized four different CdS/Fe₃O₄ photocatalysts with varying ratios of mass of CdS to Fe₃O₄. The composition and morphology of the prepared samples were investigated using X-ray diffraction (XRD), Raman spectrum, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Solid UV reflectance spectra testing found that CdS/Fe₃O₄ nanocomposites had good light absorption throughout the spectral range, promoting their photocatalytic properties. Under visible light irradiation, CdS/Fe₃O₄ (2:5) with a mass ratio of 2:5 exhibited excellent photocatalytic performance, with a degradation rate of 98.8% for rhodamine B. Furthermore, after five cycles of photocatalytic degradation reaction, the rhodamine B degradation rate remained at 96.2%, indicating that the photocatalysts have good photocatalytic stability.

A flower-like BiOBr photocatalyst (CS/BiOBr) was prepared by using the carbon material derived from corn straw (CS) as the carrier. The prepared composites were characterized by X - ray diffraction (XRD), Fourier transform infrared (FIIR) spectra, scanning electron microscope (SEM), X - ray photoelectron spectra (XPS), and UV-Vis diffuse reflectance spectra (UV-Vis DRS). The SEM analyses indicate that the introduction of CS promotes the formation of a unique flower-like structure in BiOBr, which not only optimizes the efficiency of light capture but also increases the specific surface area of BiOBr. The bandgap of the composite was narrower compared with the pure BiOBr. The CS/BiOBr composites exhibited higher photocatalytic activity than pure CS and BiOBr under visible light irradiation, and a higher first-order reaction rate constant (k) of 0.043 7 min^-1 than BiOBr (0.014 6 min^-1), and exhibited excellent stability and reusability during the cyclic run. The enhanced photocatalytic activity is attributed to the efficient separation of photoinduced electrons and holes. Superoxide radicals and holes were the major active species.

Bi₂O₃@BiVO₄ composites were synthesized using the solvothermal method with ethylene glycol as the solvent. Bi₂O₃ was grown on the surface of BiVO₄ by regulating the reaction temperature. The adsorption performance of the composite for rhodamine B (RhB) was investigated. The results indicate that the reaction temperature significantly impacts the morphology and adsorption performance of Bi₂O₃@BiVO₄. The Bi₂O₃@BiVO₄ composite prepared at 180 ℃ (180-BO@BVO) consisted of nanoparticles with an average size of 7 nm, featuring a higher concentration of oxygen vacancies on the surface, but with a lower specific surface area (only 1.2 m²·g^-1). 180-BO@BVO, with oxygen species adsorbed at surface oxygen vacancies carrying a negative charge, achieved an impressive RhB removal efficiency of up to 83.0% through electrostatic interaction with RhB. The adsorption process follows the Langmuir isotherm and the pseudo-second-order kinetic model, suggesting that it is predominantly governed by chemical adsorption. After five cycles of adsorption experiments, the removal efficiency of RhB by composites remained basically unchanged (more than 80%), demonstrating excellent regeneration performance.

吸附是一个常见且重要的物理化学过程，吸附实验也越来越多地出现在实验教学当中。然而，传统的教学模式使学生往往只能被动接受实验方案，缺乏对吸附剂选择和微观吸附机理等方面的深入理解。为此，我们提出一种基于人工智能(AI)的数字化实验设计，旨在通过生成式AI大模型的智能分析和分子动力学(MD)模拟，使学生既可以进行实验前的性能预测，又可以进行实验前后的人机对话预习与总结。学生首先通过互动式对话使用ChatGPT智能助手进行文献收集、整理、吸附剂筛选和个性化预习。随后利用MD模拟预测吸附剂性能，探索吸附机制。再对模拟预测结果进行实验验证，测试吸附动力学和热力学。最后针对实验中的问题和思考与ChatGPT智能助手互动。本实验设计实现了从人机对话的个性化预习、吸附过程的数值模拟，到实验验证，再到人机对话总结的全流程数字化教学，使学生从被动的操作执行者成长为主动的学习参与者和研究探索者，为传统实验教学的现代化和智能化提供了新思路。
