The electron donating capacity of biochar is dramatically underestimated [PDF]

, 2016
Biochars have gathered considerable interest for agronomic and engineering applications. In addition to their high sorption ability, biochars have been shown to accept or donate considerable amounts of electrons to/from their environment via abiotic or ...
