Abstract

• Biochar supported nanoscale zero-valent iron composite (nZVI/BC) was synthesized.

• nZVI/BC quickly and efficiently removed nitrobenzene (NB) in solution.

• NB removal by nZVI/BC involves simultaneous adsorption and reduction mechanism.

• nZVI/BC exhibited better catalytic activity, stability and durability than nZVI.
