简介：Novel magnetic biochars (MBC) were prepared by one-step pyrolysis of FeCl3-laden biomass and employed for Hg-0 removal in simulated combustion flue gas.The MBC exhibited far greater Hg0 removal performance compared to the nonmagnetic biochar (NMBC) under N2 + 4% O-2 atmosphere in a wide reaction temperature window (120250 degrees C). The optimal pyrolysis temperature for the preparation of MBC is 600 degrees C, and the best FeCl3/biomass impregnation mass ratio is 1.5 g/g.The mechanism of Hg-0 removal was proposed, and there are two types of active adsorption/oxidation sites for Hg-0: Fe3O4 and oxygen-rich functional groups. The role of Fe3O4 in Hg-0 removal was attributed to the Fe-3(+)(t) coordination and lattice oxygen. The C-O group could act as act as electron acceptors, facilitating the electron transfer for Hg0 oxidation.
