Nanosheets-built flowerlike micro/nanostructured Bi2O2.33 has been synthesized.
Such Bi2O2.33 possesses the high performances of iodine removal.
The high iodine removal performances originate mainly from the adsorption-induced chemical reaction.
This material has a strong selectivity to iodine in the water with largely excessive competitive anions.
This material exhibits good practicability in the iodine removal from the real contaminated waters.
