Fabrication of ZnO micronano arrays supported Tb-doped MOF films for highly selective sensing of acetone

中国化学会第十届全国无机化学学术会议

作者： Feng Zhang Jinjin Ma yangyi yang School of Chemistry and Pharmaceutical Engineering Huanghuai University School of Materials Science and Engineering Sun Yat-sen University

The difficulties in directly grown on current collector of electrode materials largely thwarts their maximum performance for energy storage. Herein, a "one for two" strategy of employing NiCoO nanowires(NWAs) both as conductive "nano-anchors" and as strain buffer "support" to synthesize electrodes of a hybrid supercapacitor(HSC) was successfully developed. Specifically, for the positive electrode, to improve the overall electrical conductivity and active surface area of MOFs, NiCoO NWAs on surface of carbon cloth as the interconnected anchors for in situ growth of MOFs nanosheets. The as-synthesized NiCoO@Ni-MOF electrode shows high areal capacitance(7.23 F cm-2 at a current density of 5 mA cm), and good rate capability. Meanwhile, NiCoO NWAs are used as the strain buffer supports for preparing core-shell NiCoO@PPy nanorod arrays as negative electrode. As a result, the HSC is successfully assembled by using the NiCoO@Ni-MOF and NiCoO@PPy as electrodes, achieving both high volumetric capacitance and energy density. This study not only presents a "one for two" strategy for effectively fabricating binder-free energy storage electrodes but also offers a route to enhance the conductivity of MOF-based electrode materials.

A luminescent Terbium-MOF film fabricated by electrodeposition method for detection of Cu2+ in water

中国化学会第九届全国无机化学学术会议

作者： Yi Wang Zhongheng Wang yangyi yang MOE Key Laboratory of Bioinorganic and Synthetic Chemistry School of Chemistry and Chemical Engineering Sun Yat-Sen University

Lanthanide metal-organic frameworks（MOFs） have emerged as very important multifunctional luminescent materials in the past decade due to their unique luminescence properties, such as large Stokes’ shifts, high color purity, and long luminescence lifetimes, make them especially attractive for sensing applications. 1,2 For practical sensor applications, it is necessary to fabricate MOFs as thin films on different types of substrates.3 These MOF films are almost always based on transition metal MOFs and cannot satisfy all the applications in sensing usage. As many of lanthanide complexes have poor film forming ability, few investigations concerning the growth of Ln-MOF films for luminescent applications were achieved so far. It is still a great challenge to prepare Ln-MOF films on supports in an easy and simple way. Herein, a series of luminescent thin films based on Tb3+ doped in Zn metallic organic frameworks with different carboxylic acids [1,4-benzenetricarboxylate,1,3,5-benzenetricarboxylate, 2,6-Naphthalenedicarboxylic Acid] are fabricated via using ordered hierarchical ZnO arrays as the substrate. The luminescent thin films Tb@MOF/ZnO（Tb doped in MOF/ZnO） are synthesized by solvothermal synthesis and postsynthetic modification（PSM） approach.4 The structure, composition and morphology of Tb@Zn（BDC）/ZnO（1）are characterized by XRD, EDS, SEM and ICP. The doping of Tb3+ ions in the hybrid films Zn（BDC）/ZnO（Zn:Tb =100:1） exhibits characteristic green emission of Tb3+ ion, and presents highly detectable luminescence responses for acetone molecules. This approach of preparing MOF film provides an inexpensive, facile strategy for fabricating new types of luminescent thin films. The luminescent thin films are first prepared successfully using lanthanide-ions doped hybrid MOF/ZnO micronano arrays films as small molecule sensor.

Sporadic E responds to the 2022 Tonga volcano eruptions recorded by the Meridian Project

With the development of modern industry, heavy metal ions such as copper ion from industrial wastes have increasingly released to the environment, which cause to a series of ecological and health-care issues. However, fast in-field sensing of environmental pollutants directly determined by the naked eyes with is still challenging. Lanthanide metal–organic frameworks（Ln-MOFs） as sensing materials for pollutant detection have recently received increasing attention because of their advantages of short response time and high sensitivity towards specific analytes. Herein, we report a luminescent lanthanide metal-organic framework（Ln-MOF） thin film of Terbium-Succinate（Tb-SA） fabricated onto FTO conductive glass via a facile one-step electrodeposition method1,2. The composition of the film was confirmed by powder X-ray diffraction3. The morphology was examined by SEM and reveals a flower-shaped thin sheet clusters on the surface. The photoluminescence experiment shows that Tb-SA films exhibits characteristic luminescence of Tb3+ and presents highly eye-detectable luminescent response towards Cu2+ ion in aqueous solution. The variations of luminescent intensities are clearly interrelated to the concentration of Cu2+ ion and well-fit with the Stern-Volmer equation4 over the range of 1×10-4M to 1×10-3 M. Furthermore, the film can be used as facile sensor for directly sensing of 0.1m M Cu（II） in water by naked-eyes under 254 nm UV-light. The potential quench mechanism was also discussed5.
