Molten salt-confined construction of biocarbon 2D based on Megathyrsus Maximus biomass for high-performance symmetric supercapacitor
Exploring infinite resources, green strategy, and inexpensive for producing 2D biocarbon nanosheets is an essential method in renewable energy. This study aims to develop a eutectic salt-induced activation process for the production of porous carbon nanosheets with well-controlled microstructure using varying ZnCl2 molarity levels. The results showed that biocarbon featuring thin nanosheets with 2D structure and a high specific surface area of 1294 m2g−1 could be obtained in eutectic salt ZnCl2 at 0.5 molarity with a specific capacitance reaching 495 Fg−1. In addition, the capacitive properties of the cells decreased when the molarity was increased to 0.7 M, leading to a decline in specific capacitance to 171 Fg−1. Based on these results, the new and low-cost strategy of eutectic salt media provided an effective method of converting guinea grass into highly valuable biocarbon in the field of electrochemical energy storage.
期刊介绍：
DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices.
The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
