Abstract
A series of Ag0@C/SiO2 adsorbents were prepared using rice husk-based C/SiO2 as supports and applied to capture iodine gas. The results demonstrated that 50%Ag0@C/SiO2 reached a record high iodine adsorption capacity (788 ± 25 mg/g) due to the synergistic effect between C/SiO2 supports and Ag0 sites. The adsorption data of Ag0@C/SiO2 can be better fitted with the pseudo first order and Langmuir models. The iodine adsorption process included the physical and chemical adsorption. The adsorption mechanism was that Ag0 reacted with I2 to form AgI. Owing to the excellent adsorption capacity, Ag0@C/SiO2 derived from rice husk could be promising iodine gas adsorbents.
