Two metal-organic frameworks (MOFs) containing rigid bis(triazole) ligand, namely {[Zn₂(L)(TP)₂(H₂O)·H₂O]}_n (1) and [Zn(L)(HTMA)]_n (2), where L=4, 4'-(3, 3'-dimethyl-(1, 1'-biphenyl)-4, 4'-diyl)bis(4H-1, 2, 4-triazole), H₂TP=terephthalic acid, H₃TMA=1, 3, 5-benzenetricarboxylic acid, were synthesized by using acid-base mixed ligands strategy and structurally characterized by X-ray single-crystal diffraction. Structural analysis reveals that MOF 1 displays a 3, 6-connected 2D structure with a new topological point symbol of (4²·6)₂(4⁸·6⁶·8), while MOF 2 presents a 2D sql topology structure. The catalytic studies reveal that 2 exhibits excellent catalytic activity for the cycloaddition reaction of CO₂ with epoxides under mild conditions. Furthermore, 2 can be reused at least three times while maintaining its catalytic ability.

Two new viologen-polyoxometalate hybrid crystalline materials: (MV)₂[HPW₂^ⅤW₁₀^ⅥO₄₀] ·2H₂O (1) and (EV)₂[Mo₈O₂₆] (2) have been synthesized by using the cations of 1, 1'-dimethyl-4, 4'-bipyridinium dichloride (methyl viologen, MV) and 1, 1'-diethyl-4, 4'-bipyridinium dibromide (ethyl viologen, EV) as the electron acceptors, and the electron-rich polyoxometalate anions as the electron donors. The structures of compounds 1 and 2 have been determined by single-crystal X-ray crystallography. Hydrogen bond interactions exist between the cations and the anions in 1 and 2. Interestingly, 2 has a photochromic performance with a light response time within 1 min. The photochromic mechanism of compound 2 has been investigated by solid-state diffuse reflection, electron paramagnetic resonance and theoretical calculation. 1 and 2 show good catalytic performance in the photocatalytic degradation of several organic dyes (methylene blue, pararosaniline hydrochloride and rhodamine 6G).

通过一步水热法制备了CeCO₃OH-rGO (还原氧化石墨烯)，并在氩气(Ar)气氛下焙烧制备得到CeO₂-rGO复合材料。采用X射线衍射、扫描电子显微镜、X射线光电子能谱以及紫外可见漫反射光谱(UV-Vis DRS)等研究了复合材料的物相组成、微观形貌、空位缺陷和光电化学特性等。对比研究了不同GO (氧化石墨烯)负载量和NH₄HCO₃添加量下所制备材料的光催化性能，发现GO负载量为10 mg、NH₄HCO₃添加量为15 mmol的样品(CeO₂-10rGO-15)具有最窄的禁带宽度(3.17 eV)，对亚甲蓝(MB)的光催化降解率达80.66%。适宜的rGO负载量有利于促进CeO₂空位缺陷的形成，也有利于光生载流子的分离，进而促进光催化性能。

全固态无负极锂金属电池(AFSSLB)是一种通过初次充电形成金属锂负极的新型锂电池，它的负极与正极容量比为1，能使任意锂化正极系统达到最大能量密度。无机固态电解质的引入使无负极锂金属体系兼具高安全性。然而，电池循环过程中的锂离子通量不均导致的界面接触损失和锂枝晶生长会不断加剧，从而造成电池循环容量迅速衰减。本文构筑了纳米化的银碳复合集流体，显著增强了全固态无负极锂金属电池中集流体-电解质界面的性能。使用该集流体的固态电池循环过程中接触良好，界面阻抗为~10 Ω∙cm⁻²。从而实现了超过7.0 mAh∙cm⁻²锂金属的均匀稳定沉积，并在0.25 mA∙cm⁻²的电流条件下实现循环200次以上。

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.
