Understanding the synergy between N-doped ultra-microporous carbonaceous adsorbent and nitrogen functionalities for high performance of CO2 sorption
Rafay Ahmed,Guijian Liu,Guijian Liu,Balal Yousaf,Balal Yousaf,Abdul Rehman,Mehr Ahmed Mujtaba Munir,Samina Irshad,Muhammad Saqib Rashid,Ayesha Imtiyaz Cheema +9 more
TL;DR: In this paper, nitrogen-doped carbonaceous adsorbents with high ultra-microporous structure were synthesized by carbonization and activation of chitosan along with urea and KOH simultaneously at various temperatures (600−900 °C).

Applying modified biochar with nZVI/nFe3O4 to immobilize Pb in contaminated soil.
TL;DR: The results highlighted that biochar-loaded nano-iron-based materials, especially BC-nZVI, was promising and environmentally friendly materials for remediating Pb-contaminated soils, which provided scientific reference and theoretical basis for the treatment of Pb’s contaminated soils around industrial sites particularly in acid rain area.

A review of biochar and its use and function in soil
TL;DR: The potential to sequester carbon as thermally stabilized (charred) biomass using existing organic resource is estimated to be at least 1 Gt/yr − 1 and biochar, defined by its useful application to soil, is expected to provide a benefit from enduring physical and chemical properties.

A review of biochars’ potential role in the remediation, revegetation and restoration of contaminated soils
Luke Beesley,Eduardo Moreno-Jiménez,Jose L. Gomez-Eyles,Eva Harris,Brett Robinson,Tom Sizmur +5 more
TL;DR: Specific mechanisms of contaminant-biochar retention and release over time and the environmental impact of biochar amendments on soil organisms remain somewhat unclear but must be investigated to ensure that the management of environmental pollution coincides with ecological sustainability.

Positive and negative carbon mineralization priming effects among a variety of biochar-amended soils.
TL;DR: In an effort to better understand the interaction of pyrogenic C and soil organic matter (OM), a range of Florida soils were incubated with a variety of laboratory-produced biochars and CO 2 evolution was measured over more than one year as discussed by the authors.
