以2-氨基对苯二甲酸(H₂ATA)为配体，通过溶剂热法合成了Zr基MOF：NH₂-UiO-66，继而以氯化钨为前驱体，通过溶剂热法实现了富含氧空位的缺陷氧化钨(W₁₈O₄₉)在NH₂-UiO-66上的原位生长，构建了具有典型Ⅱ型异质结的复合光催化剂W₁₈O₄₉/NH₂-UiO-66。通过粉末X射线衍射、扫描电子显微镜、X射线光电子能谱和紫外可见漫反射光谱对催化剂的组成与结构进行了表征。在室温常压、模拟太阳光下，以氧化苯乙烯为模型底物，对所有样品的光催化活性进行了考察，W₁₈O₄₉/NH₂-UiO-66展现了最高的碳酸苯乙烯酯产率(58 mmol·g^-1·h^-1)。

In this work, p-phenylenediamine and L-cysteine were used as raw materials, and water-soluble N, S co-doped carbon dots (N, S-CDs) with excellent performance were prepared through a one-step solvothermal method. The morphology and structure of N, S-CDs were characterized by transmission electron microscope, X-ray diffraction, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy, and the basic photophysical properties were investigated via UV-Vis absorption spectra and fluorescence spectra. Meanwhile, the N, S-CDs have excellent luminescence stability with pH, ionic strength, radiation time, and storage time. Experimental results illustrated the present sensor platform exhibited high sensitivity and selectivity in response to baicalein with a detection limit of 85 nmol·L^-1. The quenching mechanism is proved to be the inner filter effect. In addition, this sensor can also detect baicalein in biofluids (serum and urine) with good accuracy and reproducibility.

Electro-copolymerized film containing ruthenium complexes as electron-transfer (or redox) mediators and water-oxidation catalysts by an oxidative copolymerization method is presented. The addition of the redox mediator significantly improved the electrocatalytic water-oxidation activity and reduced the overpotential to 220 mV. The prepared electrode showed a water-oxidation catalytic rate constant k_obs of 31.7 s^-1 and an initial turnover frequency of 1.01 s^-1 in 1 000 s by potential electrolysis at 1.7 V applied bias vs NHE (normal hydrogen electrode). The kinetic isotope effect study suggests that the catalytic water oxidation reaction on the electrode surface occurs via a bimolecular coupling mechanism.

Herein, a layered chiral coordination polymer, [Cd₂(D-cam)₂(2, 2'-bipy)₂]_n (Cd-CP), was synthesized using a solvothermal method with camphoric acid (D-H₂cam), 2, 2'-bipyridine (2, 2'-bipy) and Cd²⁺, and Tb³⁺@Cd-CP was in-situ synthesized introducing Tb³⁺ ions. The fluorescence experiments revealed that compared to Cd-CP, Tb³⁺@Cd-CP exhibited ultra-high fluorescence performance. The luminescence sensing performance demonstrated that Tb³⁺@Cd-CP could distinguish R/S-propylene glycol (R/S-PG) by fluorescence responses, with fluorescence quenching constant of 5.3×10³ and 2.0×10³ L·mol^-1 respectively and the enantioselectivity factor (α) of 2.65. Moreover, Tb³⁺@Cd-CP demonstrated limits of detection of 9.3 and 19.0 μmol·L^-1 for R-PG and S-PG, respectively, and showed good reproducibility.

采用原位静电自组装法，再经单宁酸溶液蚀刻，构建了用于负载锂硫电池中活性物质硫的MXene Ti₃C₂T_x/中空ZIF-67(HMZ)载体。中空ZIF-67能够有效抑制MXene Ti₃C₂T_x的不可逆堆叠趋势，并通过Ti和Co元素共同化学吸附锂多硫化物，抑制穿梭效应，同时还能通过物理作用限制锂多硫化物，缓解膨胀效应。结果表明，单宁酸溶液蚀刻5 min形成的HMZ-5经载硫后在1C下能够提供615.1 mAh·g^-1的比容量，且在700次的循环过程中具有0.055%的低容量衰减率。
