Abstract
Transition metal oxides supported on TiO2 were synthesized by a sol-gel method and implied to simultaneous removal of Hg0 and HCN under low temperature and micro-oxygen conditions. The results show that catalysts that modified by manganese oxide have superior catalytic oxidation activity for both the removal of elemental mercury (Hg0) and HCN. Furthermore, the O2 can promote in the removal reaction process. The fresh and used catalysts were characterized by BET and XPS. The catalyst characterization indicated that the catalyst possessed a large specific surface area and the chemisorbed oxygen participated in the catalytic oxidation reaction. The MnOx/TiO2 catalyst was demonstrated to a good catalytic oxidant for simultaneous removal of elemental mercury (Hg0) and HCN under micro-oxygen conditions.
