New notion of biochar: A review on the mechanism of biochar applications in advannced oxidation processes
Xuerong Zhou,Yuan Zhu,Qiuya Niu,Guangming Zeng,Cui Lai,Shiyu Liu,Danlian Huang,Lei Qin,Xigui Liu,Bisheng Li,Huan Yi,Yukui Fu,Ling Li,Mingming Zhang,Chengyun Zhou,Jiahuan Liu +15 more
TL;DR: In this paper, a review of the role of biochar in catalysis is presented, which concludes that the oxygen-containing groups and PFRs on original biochar could favor the catalytic process through generating radicals, and the loaded metal would grow as the prominent active site.

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.
