实验室安全建设是实验室高效有序运行的保障。大学生作为基础教学实验室运行的主力，他们的安全素养直接影响着实验室的安全状况。在实验教学过程中构建注重安全素养培养的“实验室管理人员、教师、学生——全员、全时三位一体实验教学模式”，并在分析化学实验教学中进行了具体实践。新的实验教学模式加强了实验室管理员、教师与学生之间的沟通，通过COOP与7S实验教学方案，使学生在学习的同时沉浸式参与实验环境维护及建设、根植安全理念。利用Partial Eta Squared (η²)检验和多元Logistic回归模型分析发现，实验过程操作规范性和操作区有序度对学生安全素养影响明显。实践证明，该模式有助于培养学生良好的实验习惯和安全素养，增加学生在实验室中的责任感和获得感，实现管教增质、教学相长、安全铸魂的教学目标，使实验室人员可以把安全时刻掌握在自己手中，实验室安全运行水平有效提升。

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.
