简介：A long-standing and predominant predicament that impedes the application of metal selenides for the elemental mercury (Hg0) sequestration from industrial flue gases is the failure to simultaneously optimize the preparation simplicity and sequestration performance of metal selenides. Based on the critical hypothesis that coordinatively unsaturated selenide ligands play a vital role in initiating the Hg0 immobilization process, this work reports the adoption of a facile precipitation method for the synthesis of the copper selenide (CuSe) sorbent. The low sample preparation temperature serves for the crystallinity adjustment, which hence enriched the copper selenide surface with coordinative non-stoichiometry and unsaturated selenide ligands. The facile preparation logic with relatively extensive applicability can be expected for the synthesis of various metal selenides in addition to CuSe, hence marking the first attempt stepping towards the real-world application of metal selenides for
