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 to 250 °C. 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 about 100% to about 78%. By contrast, CuCl2-promoted samples maintained a hg0 oxidation efficiency of about 100% during the SO2 deactivation cycle due to the high reactivity of Cl-.
