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 ℃.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-.
