Abstract: In this study, a series of CuCl2-modified MnOx–CeOx nanorods were synthesized for the oxidation of Hg0. The addition of CuCl2 resulted in an enhancement in the catalyst's Hg0 oxidation ability, and Hg0 oxidation efficiency reached >97% from 150 oC to 250 oC. In the MnOx–CeOx catalysts, Mn4+ played the role of the active species for Hg0 oxidization, but in the CuCl2-doped catalysts Cl- also contributed to Hg0 oxidation, conferring the superior performance of these samples. The introduction of SO2 led to a decrease in the availability of Mn4+, and the Hg0 oxidation efficiency of MnOx–CeOx decreased from ~100% to ~78%. By contrast, CuCl2-promoted samples maintained a Hg0 oxidation efficiency of ~100% during the SO2 deactivation cycle due to the high reactivity of Cl-.
