课程思政的有效融入是教学质量提升和高素质人才培养的关键。我们以“电动势法测定化学反应的热力学函数”这一实验项目为例，构建了一次深入的实验探究与思政教育相结合的教学实践活动。通过对电动势测定原理和方法的探讨以及反应热力学量的导出，学生们不仅深化了对相关基础理论知识的理解，提升了他们解决实际问题的实验技能和创新能力;同时强化了学生的家国情怀以及责任担当意识。

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.
