Description of Publication:The Fe3O4-xSey as obtained exhibited an advantageous core-shell like spherical structure, in which the interior Fe3O4 core kept unchanged during the selenization process and warranted the recyclability of Fe3O4-xSey, while the exterior part exposed to Hg0 was selenized into iron diselenide (FeSe2) that has high affinity towards Hg0. Moreover, the selenization process introduced more mesopores that were favorable for Hg0 migration and accommodation. Co- benefitted from these perspectives, the Fe3O4-xSey exhibited a Hg0 adsorption capacity and uptake rate as high as 8.8 mg/g and 3.7 μg g/min, respectively, far exceeding the capacity and rate of bare Fe3O4 and traditional Hg0 remediators.
