The most reliable sources of natural iodine are sea vegetables and seafood. Other common sources are typically high in iodine because they were grown in iodine-rich soil, fed fish in their diet (i.e., chickens and eggs), or fortified (grains).
Iodine-doped starch-based carbon material, method for preparing the same, and use thereof
The application provides an iodine-doped starch-based carbon material and a preparation method and application thereof, and relates to the technical field of starch-based carbon materials. The method comprises the following steps: mixing starch, an iodine source and a water-soluble dispersant in a solvent, aging, drying and crushing to obtain a purple red to blue purple inclusion precursor; and then performing gradient carbonization treatment in an inert atmosphere to obtain the iodine-doped starch-based carbon material. The application realizes the inclusion and molecular-level anchoring through the van der Waals force between the spiral cavity of the linear starch and the iodine element, and relies on the water-soluble dispersant to form a physical encapsulation layer on the surface of the starch in situ in the low-temperature carbonization stage, cooperates with the high-temperature carbonization process, and inhibits the volatilization of the iodine element to realize the doping of high iodine content. The obtained material is characterized in that the iodine is embedded in the carbon skeleton in a P-pi conjugate state, the conductivity is significantly enhanced, the carrier concentration is improved, and the sodium ion storage capacity is improved, so that the reversible specific capacity is improved and the first circle coulombic efficiency is improved.
