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。

由于电催化剂中的非晶区和结晶区具有不同的物理化学性质，因此非晶化/结晶化工程成为提高电解水催化动力学的重要策略。然而，在微观环境中有效地调控催化剂的结晶度仍然是一个严峻的挑战。本文介绍了一种可调节结晶度的新型CrS/CoS₂异质结构，该异质结对氢气析出反应(HER)和氧气析出反应(OER)都具有高效的催化活性。Cr―S―Co键的重新分配引起的d带中心移动有助于调节中间体H*和OOH*在催化剂表面的吸附能力，从而优化HER和OER的决速步骤。在最佳条件下，非晶态CrS和高度结晶的CoS₂异质结(A-CrS/HC-CoS₂)在HER和OER均表现出优异的催化活性，分别为90.6 mV (10 mA∙cm⁻²，HER)和370.5 mV (50 mA∙cm⁻²，OER)。非晶/高晶结构有利于A-CrS/HC-CoS₂在水电解过程中的结构和成分演变，因此具有出色的稳定性。作为甲醇辅助节能制氢装置中的双功能催化剂，A-CrS/HC-CoS₂仅需1.51 Ⅴ的低槽电压即可达到10 mA∙cm⁻²的电流密度，证明其是理想的金属基催化剂的候选材料。本研究为双功能过渡金属化合物电催化剂在非晶态/晶态异质结构中通过结晶度调控来提高催化活性和稳定性提供了重要启示。

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。

围绕以学生发展为中心的创新人才培养目标，我们在多年持续教改和探索基础上，提出了“综合+探究”式、模块化分析化学实验教学。要求学生在完成既定的综合实验基础上，针对实验过程中发现的问题，自主设计探究方案，进行个性化实验探究；同时，将研究生组会研讨模式融入到本科生实验教学中，增设方案答辩环节，实现“一生一方案”的教学。该教学方法实施以来，成效显著，不仅激发了学生学习兴趣和实验潜能，锻炼了实验思维和知识运用能力等综合实践能力，而且开启了对求异思辨、创新能力的培养，教学模式得到普遍欢迎和首肯。

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.
