Highlights BC-G@Fe0 nanocomposite was produced through two carbothermal reduction routes. The biomass impregnating-carbonizing route produced graphene-encapsulated iron carbide (Fe3C) nanoparticles. The pyrolyzing-biochar-impregnating-carbonizing route produced graphene-encapsulated nanoscale zero-valent iron particles. BC-G@Fe0 nanocomposites exhibited good heavy metal ion removal performance.
