Abstract

•	Characteristics and mechanisms for the generation and consumption of EPFRs were proposed.
•	To favor g3-type EPFRs formation, the quantity of Fe(III) and aromatic compounds of the biomass should be matched.
•	The g3-type EPFRs on hydrochars played a major role in the Fenton-like reaction.
•	The external EPFRs of hydrochars were consumed easily while the internal EPFRs persisted during long-term storage.
