Structure-activity relationships, product species distribution and the mechanism of effect of multi-component flue gas on Hg⁰ adsorption and oxidation over CuO/ACs.

ABSTRACT: A series of Cu-doped activated cokes (CuO/ACs) were synthesized via an impregnation method and applied for the removal of elemental mercury (Hg⁰). Structure-activity relationships between Hg⁰ removal and CuO/AC surface characteristics were identified. Hg⁰ removal over CuO/AC occurs through a combination of physisorption and chemisorption and is mainly dominated by chemisorption. It was found that 1 nm micropores facilitate Hg⁰ physisorption. Hg⁰ could weakly adsorb onto an O-terminated crystal layer, whereas strongly adsorb onto Cu-terminated single highly dispersed, clustered and bulk CuO (110) crystal planes via the Mars-Maessen mechanism. Product distributions and mechanisms of Hg⁰ adsorption and oxidation o
