简介：Metal sulfides (MSs) can efficiently entrap thiophilic components like elemental mercury (Hg0) and realize environmental remediation. However, there is still a critical problem challenges the extensive application of MSs in related areas, i.e., how to self-regulate their water (H2O) resistance without complexing the sorbent preparation procedure. This work for the first time developed an in-situ acid etching method that self-engineered the water affinity of MSs through changing the interfacial interaction between MSs and Hg0/H2O. The introduction of abundant under-coordinated sulfur onto the sorbent surface was the primary reason accounting for the significantly improved H2O resistance. The highly water-resistant and cost-effective MSs as prepared can serve efficient Hg0 removal from industrial flue gas in the future.
