摘要
Hollow microbeads, derived from fly ash emitted by power plants, are hollow microbeads composed of various compounds including SiO2 and Al2O3. These microspheres exhibit a high specific surface area and stable chemical properties. In this work, HM-MoS2 was synthesized through a two-step hydrothermal method to address the issues of low adsorption efficiency and high operational costs associated with the utilization of hollow microbeads in actual power plant applications. The experiments demonstrated that under simulated power plant flue gas conditions, the adsorption efficiency of HM-15 for elemental mercury (Hg0) exceeded 96%. Additionally, HM-15 displayed resistance to SO2 and NO gases, indicating its potential as a mercury adsorbent material with promising industrial applications.
