Chemistry and materials options of sustainable carbon materials made by hydrothermal carbonization
TL;DR: It will be shown that HTC does not only access carbonaceous materials under comparatively mild hydrothermal conditions, but also replaces the more technical and structurally well-defined charring by a controlled chemical process, leading to very different morphologies with miscellaneous applications, including modern carbon nanocomposites and hybrids.
