A 1D coordination polymer (CP), (TBA) [Bi(bp4do)Br₄] (1), was synthesized by the assembly of 4, 4' - bipyridine -N, N'-dioxide (bp4do) and Bi³⁺ (TBA⁺=tetrabutylammonium). 1 exhibits a red luminescence with a quantum yield of up to 69%. A solid-state thin-film sensor (1/PVP) with extremely high luminescence stability was prepared by combining 1 with polyvinyl pyrrolidone (PVP). 1/PVP has a wide - range sensing capability for 11 NH₃/amine vapors with rapid response. During the sensing process, its luminescence color changed from red to blue, which was easy for naked -eye observation. The sensing mechanism is NH₃/amine-induced collapse of the framework of 1. Furthermore, 1/PVP has been successfully applied to monitoring food freshness such as meat/aquatic products.

锂浆料电池(LSSFBs)具有应用于大规模储能系统的潜力。然而，LSSFBs的电化学性能受限于活性材料本征导电性差以及活性材料与导电添加剂之间的不稳定接触。本文设计了碳包覆的二氧化锡/多壁碳纳米管(C-SnO₂/MWCNTs)复合材料作为LSSFBs负极材料。在该复合材料中，SnO₂纳米颗粒均匀分布在(MWCNTs)表面，同时SnO₂颗粒外表进行碳包覆。纳米尺寸赋予SnO₂更多反应活性位点。此外，碳纳米管和碳包覆层共同构建稳定的导电网络。这种导电网络有效改善SnO₂的电子转移动力学，并抑制其在充/放电过程中的体积膨胀，从而提高倍率和循环性能。此外，MWCNTs增强浆料电极的悬浮稳定性。这些优势赋予LSSFBs良好的倍率和循环性能。这项工作为优化LSSFBs的浆料电极提供了一种具有前景的策略。

高能量密度、高功率密度的“双高”锂离子电池(LIBs)的实现依赖于创新突破高容量、高倍率及长循环寿命电极材料。插入型负极，以d⁰过渡金属氧化物为代表，含有强金属-氧键，表现出高循环稳定性和高倍率性能。然而，由于金属离子变价较少，其比容量相对较低。转化-合金型负极，以p区金属氧化物为代表，具备高理论比容量，但嵌锂过程中的相团聚和体积膨胀易导致容量快速衰减和倍率性能不佳。通过引入插入型或转化型功能基元构建双金属氧化物负极，可以优化电极中的电子/离子传导，从而改善循环性能和倍率性能，有望实现负极材料高容量、高倍率及长循环的统一。本文通过对各类金属氧化物中的化学键及电子结构特征进行分析，并提出一种新的图示表达方式，将负极锂离子插脱嵌的电化学反应储能过程表达为态密度(DOS)图示。文章阐述了双金属氧化物负极的多步储锂机制，并结合近期相关研究进展，为发展高容量、高倍率及高稳定的双金属化合物负极提供理论参考和实践依据。

对本科教学中涉及的开链季铵碱和环状季铵碱的消除机理进行了分析；对于环状季铵碱，当有两种反式共平面的β-H时，倾向于消除取代基较多的碳上的氢，得到扎伊采夫取向的烯烃为主要的产物，该结论也通过计算化学的手段得到佐证。该论文对Hofmann消除的本科教学是个丰富和支撑。

高效液相色谱实验是化学专业的重要仪器分析实验，然而目前实验教学中的传统高效液相色谱实验往往分析对象过于简单，离实际应用较远，且缺乏前沿性和趣味性。更重要的是，经典教学实验中的色谱定量分析基于物理/化学分离，其效率和通用性有待提高，且无法落实“数字化”技术在高等教育中的应用。因此，我们结合“数字化”技术设计了一个新的色谱实验——“数学分离”赋能的高效液相色谱法测定化妆品中的苯二酚异构体。传统高效液相色谱法测定化妆品中非法添加的对苯二酚、邻苯二酚、间苯二酚时存在色谱峰重叠、未知干扰影响、方法难以移植等问题。本实验针对上述问题，采用化学计量学“数学分离”技术解析高效液相色谱数据，无需对样品进行繁琐预处理，便能在色谱峰重叠和存在未知干扰的情况下获得各成分的完全选择性信号，进而实现复杂化妆品体系中三种同分异构体的精准定量。本实验将传统实验进行数字化改进，培养学生创新思维、提升学生的数智素养；通过“数学分离”打造了强大的“3S+3A”分析方法，不仅提升了学生综合解决问题的能力，也为色谱检测标准方法的制定提供了创新思路；立足于真实的化妆品检验场景，培养学生的实践能力与职业素养，并深入贯彻绿色分析化学的理念。

Two [FeFe]-hydrogenase compounds with 2-cyanobenzyl groups, {Fe₂[(SCH₂CH₃)(SR)](CO)₆} (1 or 1′, which are the crystalline states from petroleum ether and dichloromethane solution, respectively) and {Fe₂[(SCH₂CH₃)(SR)](CO)₅(PPh₃)} (2) (R=2-cyanobenzyl), were synthesized and characterized by infrared spectroscopy, UV-Vis spectroscopy, single-crystal diffraction, powder X-ray diffraction, etc. Their performances as photocatalysts for H₂ production through water splitting were evaluated. The results showed that 316.8 μmol of H₂ was produced on compound 1 after 3 h of illumination, with a catalytic efficiency of 25.1 μmol·mg^-1·h^-1 and a turnover number (TON) of 36.8. The replacement of carbonyl with PPh₃ could significantly improve the catalytic performance of the complex, and 705.0 μmol of H₂ was produced on 2 after 3 h of illumination, with a catalytic efficiency of 37.9 μmol·mg^-1·h^-1 and a TON of 81.8.

Developing high-performance electrocatalysts for the alkaline hydrogen oxidation reaction (HOR) is essential for advancing alkaline hydrogen fuel cells. Here, we report the synthesis of ruthenium (Ru) catalysts with tuned crystallinity and oxidation degree. By combining template-assisted synthesis with controlled thermal treatment, amorphous, partially crystalline, highly crystalline, and partially oxidized Ru products were successfully obtained. Catalysts with moderate crystallinity and partial oxidation exhibit enhanced catalytic activity toward the alkaline hydrogen oxidation reaction. The optimized Ru-RuO₂ catalyst achieved a mass activity of 81.66 mA·mg_Ru^-1, which was 2.27 times that of commercial Pt/C under identical conditions. The improved activity is attributed to the synergistic effect of moderate crystallinity and partial oxidation, which favors a favorable Tafel-Volmer reaction pathway.
