简介：A fundamental obstacle that restricts the use of metal selenides for gaseous elemental mercury (Hg0) immobilization is the failure to take both the optimization of intrinsic structure favorable for Hg0 diffusion and adequate exposure of metal selenide towards Hg0 into consideration. In this work, a Ti3C2 MXene/Cu2Se sorbent for Hg0 sequestration was synthesized via a Lewis acid etching route combined with room-temperature selenization pathway. During this strategy, copper chloride plays a dual role, i.e., an etching agent for the Ti3C2 MXene synthesis and a precursor for Cu0 decoration. Cu2Se precursors (Cu0) were dispersedly and firmly pre-anchored on the substrate, effectively avoiding the agglomeration and warranting excellent dispersion of Cu2Se. Compared with pristine Cu2Se, Ti3C2 MXene/Cu2Se exhibits advantageous structural characteristics fully boosting Hg0 diffusion kinetics.
