Elucidating d-π conjugated two-dimensional 2,3,6,7,10,11-hexahydroxytriphenylene based conductive metal-organic framework for hybrid supercapacitors
Electrochemical energy technology demands highly proficient and stable systems which ultimately rely upon the discovery and development of promising electrode materials. Here, we report a two-dimensional conductive nickel- metal organic framework (Ni-MOF) for energy storage application. A novel Ni- based MOF was synthesized by utilizing a distinctive ligand 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP termed as Ni3(HHTP)2. The highly conductive, porous and stable two dimensional -conjugated structure of HHTP makes Ni3(HHTP)2 an auspicious contender for energy storage applications. We characterize the Ni3(HHTP)2 developed through hydrothermal route for its structural properties and then explore its energy storage profile by fabricating the hybrid energy storage device. The Ni3(HHTP)2 based asymmetric device exhibits the capacity of 194 C/g providing the energy (Es) and power density (Ps) of 43 Wh/kg and 2400 W/kg, respectively. We then scrutinize its capacitive and diffusive components by calculating regression parameters k1 and k2 using Dunn’s model to bring further insight into the electrochemical characteristics of the electrode material. Ni3(HHTP)2 is an appealing member of 2D conductive MOFs to utilize for energy storage applications.
期刊介绍：
The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied.
Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
