Humin: No longer inactive natural organic matter

Chemosphere, 2021
The discovery of the function of humin (HM), an insoluble fraction of humic substances (HSs), as an extracellular electron mediator (EEM) in 2012 has provided insight into the role of HM in nature and its potential for in situ bioremediation of pollutants.

Humin‐promoted microbial electrosynthesis of acetate from CO2 by Moorella thermoacetica

Biotechnology and Bioengineering, 2022
Humin, an insoluble fraction of humic substances at any pH, has been reported to be an extracellular electron mediator (EEM) that functions in carbon dioxide (CO2)‐fixing acetogenesis. Here, we show that humin promotes the microbial electrosynthesis (MES)

Humin from hydroxymethylfurfuraldehyde

Recueil des Travaux Chimiques des Pays-Bas, 1946
AbstractPure hydroxymethylfurfuraldehyde when heated in aqueous solution under pressure to 130° in presence of a small amount of oxalic or hydrochloric acid affords a black, carbonaceous humin, which agrees completely in characteristics and in composition with the humin produced as a by‐product in the preparation of laevulic acid by boiling hexoses ...

Reprocessable humins thermosets and composites

Composites Science and Technology, 2021
Reduction of polymeric waste together with industrial by-products valorization are the main objectives of competitive researches. In this perspective, this work reports the preparation of sustainable thermoset resins and composites having reprocessing ability. Reprocessable humins-based thermoset resins were synthesized for the first time.

The Overlooked Role of Humin in Dark Hydroxyl Radical Production during Oxygenation.

Environmental Science and Technology
Humin, endowed with abundant redox functional groups, can be reduced anaerobically under dark. When reduced humin encounters O2, the possibility of ·OH formation arises.
