Abstract
In this work, a simple high-temperature calcination method was used to produce metallic molybdenum disulfide (1 T-LixMoS2). Experiments and simulations show that 1 T-MoS2 has stronger surface activity and enhances the adsorption capacity of Hg0, thereby effectively removing elemental mercury (Hg0) in coal-fired flue gas. Sample ML-100 could maintain a mercury removal efficiency of approximately 92% after 6-cycle experiments, and approximately 97% efficiency could be maintained throughout a long-term experiment. The proposed method converts the 2H phase to the 1 T phase by doping commercial MoS2 with lithium ions, thereby improving the removal efficiency of elemental mercury in the flue gas.
