Study on Energy Storage properties of Metal-organic frameworks nanofluids (UIO-67/Water and UIO-67/Methanol) by an experimental and theoretical method
Journal of Materials Science, 2021Co-Authors: Fei Yan, Qiang Wang, Feipeng Wang, Zhengyong HuangAbstract:Porous nanomaterials have broad application aspects in Energy Storage and conversion. In this paper, the Energy Storage characteristics of two kinds of Metal-organic Frameworks (MOFs) nanofluids were studied through experiments and molecular simulation (MS). Firstly, UIO-67/water and UIO-67/methanol nanofluids were prepared, the structural characteristics of UIO-67 were studied, and the results showed that the Metal-organic Frameworks of UIO-67 is stable under 770 K. Then, the Energy Storage Capacity of the two kinds of nanofluids was studied experimentally. The results indicated that the Energy Storage Capacity of UIO-67/water nanofluids decreased with 0.83% and 3.60% mass fractions nanoparticles at 288 K-360 K. However, that of UIO-67/methanol nanofluids containing 1.60% and 5.28% mass fractions nanoparticles showed an enhancement trend at 250 K-330 K. Meanwhile, the changes of Energy Storage Capacity are proportional to the mass fraction of UIO-67 nanoparticles. Finally, about the Energy Storage capacities of UIO-67/water and UIO-67/methanol nanofluids, the results retrieved by molecular simulation are in good agreement with the experimental ones, which provides an explanation for the inconsistency of the Energy Storage characteristics of the two kinds of nanofluids. The research method in this paper provided a reference for studying the thermophysical properties of nanofluids mixed with porous materials, and the results should have some practical interest.

High performance organic-inorganic hybrid material with multi-color change and high Energy Storage Capacity for intelligent supercapacitor application
Journal of Alloys and Compounds, 2021Co-Authors: Xiaoqian Zhao, Qingfu Guo, Xiaoyan Yang, Guangming NieAbstract:Abstract As a kind of multifunctional supercapacitor, electrochromic-supercapacitor device (ESD) can be used to visually estimate the Energy Storage level of the device through the color change. Currently, low Energy Storage Capacity limits the practical application of ESD. Here, WO3 with oblate shape morphology formed by the aggregation of nanoclusters is successfully prepared by hydrothermal synthesis. Then WO3-poly (5-cyanoindole) (P5ICN/WO3) hybrid material is obtained by electrochemical polymerization P5ICN on the surface of WO3. Due to the synergistic effect of P5ICN and WO3, P5ICN/WO3 hybrid material shows enhanced charge transfer rate, multi-colors change (blue-green, yellow and green) and good supercapacitive properties (specific capacitance is 89.2 mF cm−2). An asymmetric ESD is successfully constructed based on P5ICN/WO3, which also shows good electrochromic and supercapacitive properties, such as high specific capacitance, Energy density and power density. The color of ESD can change between yellow and dark green during charge-discharge process. In practical application, the intelligent monitoring of the Energy Storage state of device is achieved by the color variations or transmittance change of this ESD. And the charged ESD also can power a LED, indicating the feasibility of practical application.

A novel solid-state electrochromic supercapacitor with high Energy Storage Capacity and cycle stability based on poly(5-formylindole)/WO3 honeycombed porous nanocomposites
Chemical Engineering Journal, 2020Co-Authors: Qingfu Guo, Xiaoqian Zhao, Debao Wang, Guangming NieAbstract:Abstract Novel honeycombed porous poly(5-formylindole) (P5FIn)/WO3 nanocomposites are successfully prepared through combining hydrothermal synthesis and electrochemical polymerization. The morphology and structure of prepared P5FIn/WO3 nanocomposites are characterized by SEM, TEM, FTIR, Raman spectra, XRD and XPS. Due to the synergistic effect of P5FIn and WO3, the prepared nanocomposites exhibit excellent electrochemical, electrochromic, supercapacitive properties and cycle stability. The areal specific capacitance of the nanocomposites is 34.1 mF cm−2. After 5000 cycles charge and discharge, the nanocomposites can still maintain 93% of its initial capacitance value. A high coloration efficiency (137 cm2 C−1) is also shown when the nanocomposites reversibly switches among dark green, yellow and yellow green. The fabricated electrochromic supercapacitor based on P5FIn/WO3 and poly(3,4-ethylenedioxythiophene) (PEDOT) shows high specific capacitance (10.38 mF cm−2), high coloration efficiency (627 cm2 C−1) and stable cyclic stability up to 5000 charge/discharge cycles. By means of color change and transmittance change during the charging and discharging process, the smart visual monitoring of the Energy Storage state of the supercapacitor is realized. After charged, the supercapacitor can light up a LED, indicating good practical application ability. The fabricated electrochromic supercapacitor may have practical application in electronics fields due to its high Energy Storage Capacity and cycling stability.
