本文采用静电纺丝与水热法相结合的策略，成功制备了具有双功能的TiO₂/CdIn₂S₄ S型异质结光催化剂，用于耦合产氢与香兰醇(VAL)选择性氧化为香兰醛(VN)。实验结果表明，含0.5 wt% CdIn₂S₄的复合材料表现出最佳光催化性能，其产氢速率达403.36 μmol g⁻¹ h⁻¹，同时VAL转化率为90.99%。实验与密度泛函理论(DFT)计算证实，S型异质结结构可有效促进光生电荷的迁移与分离，显著提升电荷分离效率。在该体系中具有更强氧化能力的光生空穴被保留下来，用于催化VAL转化为VN，而具有更强还原能力的电子则用于光催化产氢反应。本研究提出了一种将光催化产氢与有机化合物选择性转化相结合的新策略，为开发高效太阳能驱动的新型光催化系统提供了创新思路。

Hydroxyapatite nanoparticles (HAP NPs) were synthesized by a one‐step hydrothermal method. The surface of HAP NPs was grafted —SH and —COOH chelating groups via in situ surface‐modification with iminodiacetic acid (IDA) and 3‐mercaptopropyl trimethoxysilane (MPS) to afford dual surface‐capped nano‐amendment HAP‐IDA/MPS. The structure of HAP‐IDA/MPS was characterized, and its adsorption performance for Hg²⁺, Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, and Cd²⁺ was evaluated. The total adsorption capacity of 0.10 g HAP‐IDA/MPS nano‐amendment for Hg²⁺, Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, and Cd²⁺ with an initial mass concentration of 20 mg·L^-1 reached 13.7 mg·g^-1, about 4.3 times as much as that of HAP. Notably, HAP‐IDA/MPS nano‐amendment displayed the highest immobilization rate for Hg²⁺, possibly because of its chemical reaction with —SH to form sulfide, possessing the lowest solubility product constant among a variety of metal sulfides.

面向“双碳”目标下能源开发与碳减排的协同需求，针对物理化学课程传统相图知识教学“重理论、轻应用”的问题，本文基于“可燃冰开采与CO₂封存”这一国家重大战略课题，构建“理论知识-技术应用-课程思政”三位一体教学框架：通过解析CO₂和CH₄水合物相平衡曲线与CO₂气液相平衡曲线，阐明CO₂置换法开采可燃冰及CO₂封存技术的热力学、动力学机制，横向对比可燃冰开采与应用技术现状，紧跟科学研究发展前沿，引导学生挖掘“碳封存技术的地缘政治意义”等思政议题。通过对接相图理论与国家战略需求，探索物理化学理论教学与课程思政深度融合的教学实践创新，强化学生对多相平衡原理的工程应用认知，培养学生在能源绿色转型中的创新思维与责任担当，为“新工科”背景下化工专业课程改革提供参考路径。
