Fabrication of Cu2S hollow nanocages with enhanced high-temperature adsorption activity and recyclability for elemental mercury capture

Transition metal sulfides have attracted great interest in nonferrous smelting industries for elemental mercury (Hg0) capture owing to their high activity, low cost and resistance to SO2. However, the major obstacle was the deactivation of active sites in adsorbents after the use or at high temperature. Herein, we fabricated rhombic dodecahedral Cu2S hollow nanocages by using high-quality Cu2O crystals as sacrificial templates. Benefiting from...
