Depicted as large polymers by the traditional model, humic substances (HS) tend to be
considered resistant to biodegradation. However, HS should be regarded as …

Soil contamination with heavy metals and organic pollutants has increasingly become a
serious global environmental issue in recent years. Considerable efforts have been made to …

Soils and sediments worldwide contain appreciable amounts of thermally altered organic
matter (chars). Chars contain electroactive quinoid functional groups and polycondensed …

Biochar influences soil fertility, N2O emissions, and atmospheric CO2 budgets, and because
of its quinone and aromatic structures, it is redox-active. Here we demonstrate that biochar …

Pyrogenic carbonaceous matter (PCM) includes environmental black carbon (fossil fuel
soot, biomass char), engineered carbons (biochar, activated carbon), and related materials …

Hydrochar and pyrochar are two typical biochars, and possess different intrinsic structures
and chemical properties as well as pollutant removal abilities. However, their structural …

Biochar functionalized with electroactive components is gaining increasing attention owing
to its versatile redox roles and tuneable structural configurations. In this review, we …

Biochar derived from the pyrolysis at 500° C with fresh biogas slurry and residue, was
conducted to investigate its potential role in mediating the speciation and mobilization of As …

Encompassing high priority research areas such as bioenergy production, global warming
mitigation, and sustainable agriculture, biochar has received increased worldwide interest in …

Recent research has demonstrated that black carbons catalyze the transformation of a range
of nitrated explosives sorbed to the carbon surfaces in the presence of sulfides. Although …
