Co0 anchored on Co/N co-doped porous carbon material induces H migration to accelerate sulfite oxidation and Hg(ii) adsorption in flue gas desulfurization

The low oxidation rate of (NH 4 ) 2 SO 3 and the coexistence of Hg( ii ) in desulfurization liquids restrict sulfur recovery for use as a high-value fertilizer.
