Abstract
The invention provides a two-dimensional chalcogenide, which is a crystalline material, and has a chemical formula of (NH4)2[Sn3S7]·(C4H13N3)1.41, cell parameters of a=b=13.2307(10) Å, c=19.335(2) Å, α=β=90°, and γ=120°, and space group of P63/mmc. The invention further provides a method for preparing the two-dimensional chalcogenide and use thereof in the adsorption of iodine vapor. The two-dimensional chalcogenide of the present invention is capable of removing iodine vapor of various concentrations (as low as 400 ppm) over a wide range of temperatures (25° C.-75° C.), without desorption of iodine after standing for a long time.
