英文摘要: Abstract(#br)This paper presents a study on the effect of preparation method on the structure and photocatalytic activities of BiOI and Bi 5 O 7 I photocatalysts for elemental mercury (Hg 0 ) removal in a wet bubbling reactor. Two visible-light-driven BiOI photocatalysts (BiOI-HAc and BiOI-EG) via either glacial acetic acid (HAc) coprecipitation or ethylene glycol (EG) hydrothermal synthesis as well as their derivative samples (Bi 5 O 7 I-HAc and Bi 5 O 7 I-EG) were synthesized, respectively. The photocatalysts were characterized by N 2 adsorption-desorption analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV–vis diffuse reflectance spectra (DRS), photoelectrochemical measurement and...
