文摘

The removal efficiency of the as-prepared BiOI/BiOIO3 photocatalyst reached up to 98.53% and 100% under visible light and UV irradiation respectively. The exposure mechanism of the dominant reactive facets of BiOI/BiOIO3 was analyzed in detail. The mechanism of Hg0 oxidation by BiOI/BiOIO3 was proposed.
