Pyrolyzed biomass-derived nanoparticles: a review of surface chemistry, contaminant mobility, and future research avenues to fill the gaps

Abstract

Highlights The surface functionality of pyrolyzed biomass-derived nanoparticles (PBNPs), described here as those derived from bulk biochar and activated carbon, differs from parent material. The literature on PBNPs derived from biochar is growing, unlike that of activated carbon derived PBNPs. There is a need for better understanding of co-transport of contaminants, photochemistry, and toxicity of PBNPs.
