New progress has been made in the preparation of carbon gel materials

The left image demonstrates the extremely low density of the carbon gel material, which is so light that it can easily rest on a dandelion. The right image illustrates the charge and discharge performance of the magnetic carbon aerosol obtained after calcination. From this data, we can determine that at a current density of 1 A/g, the material exhibits a specific capacitance of 333.1 F/g.
Supported by the National Natural Science Foundation of China, the "973" Major Research Project, and the Chinese Academy of Sciences, Dr. Wang Xiangke, a professor at the Institute of Plasma Physics, Chinese Academy of Sciences, led a research team including Ph.D. student Wu Xilin from the University of Science and Technology of China. They collaborated with Professor Xu Anwu to develop carbon gels with enhanced mechanical and electrical properties using hydrothermal methods. The findings were published in the prestigious journal ACS Nano (2013, 7, 3589–3597).
The researchers successfully transformed biomass, specifically watermelon, into carbon hydrogels and aerogels using a hydrothermal process. These materials exhibit excellent mechanical strength and hydrophilicity. Microstructural analysis revealed that the three-dimensional carbon structure consists of hydrophilic nano-carbon fibers and nano-spheres arranged in a cross-linked porous network. This unique structure allows for high porosity, enabling the material to act like a sponge, absorbing large amounts of moisture and other ions or molecules. When iron ions are adsorbed onto the hydrogel and then subjected to calcination, a magnetic carbon aerogel is formed. This material shows remarkable electrochemical performance, making it a promising candidate for supercapacitor applications. With a specific capacitance of 333.1 F/g at 1 A/g, it also offers advantages such as good mechanical properties, biocompatibility, and low cost, making it suitable for a wide range of applications including adsorbents, catalyst supports, sensors, biopharmaceuticals, and environmental remediation.
This groundbreaking work has drawn significant attention from researchers both in China and abroad. Chemical & Engineering News, a publication of the American Chemical Society, highlighted the study, stating that this composite aerogel could represent a promising material for energy storage applications.
