Abstract

A novel adsorbent based on Ag-loaded SBA-15 was prepared by a facile wet chemical method for the removal of elemental mercury (Hg0, the most challenging form) for the first time. The adsorbent shows excellent Hg0 removal capacity (>60 μg g−1 at 150 °C) in real flue gas and cyclic performance.
