2021-10-7 · The peak of magnetite (4 4 0) emerged and rapidly sharpened at 2.5 min. However, the peak of hematite (104, 110, 116) decreased sharply because the hematite was reduced by biomass to a greater degree over 5.0 min than at 2.5 min. The characteristic peak of hematite (104, 024) gradually diminished and finally vanished within 7.5 min.
