Elemental mercury removal by I--doped Bi2WO6 with remarkable visible-light-driven photocatalytic oxidation

Yili Zhang et al.

Summary: In this study, iodine-doped Bi2WO6 composites were synthesized through a one-step hydrothermal method to evaluate their photocatalytic efficiency in gas-phase elemental mercury removal under visible-light irradiation. The results showed that 1.0 wt.% iodine-doped Bi2WO6 exhibited the optimal Hg-0 removal efficiency due to reduced potential energy in the conduction band, decreased recombination rate of electron-hole pairs, and accelerated charge transfer. The density functional theory calculations suggested that iodine doping occurred in the (WO4)(2-) layer, facilitating the adsorption of oxidized HgO on the surface of the doped Bi2WO6.
