Fig. 4: Vapor iodine sorption study of the V2D-BBL structure.
From: Vertical two-dimensional layered fused aromatic ladder structure

a Gravimetric iodine uptake of the V2D-BBL structure (purple) and PIN (black) as a function of exposure time at 348 K and ambient pressure. Inset: the photographs of iodine release in EtOH by sonication for 10 s. b Comparison of saturation time and iodine uptake (data taken from Supplementary Table 3). c TGA curve of the I2@V2D-BBL structure under air atmosphere with a ramping rate of 10 °Ϲ min−1. d Recyclability of the V2D-BBL structure for iodine adsorption by vapor sublimation at 348 K. e Deconvoluted I 3d XPS spectrum. f FT-IR spectra of the V2D-BBL structure, I2@V2D-BBL structure and regenerated V2D-BBL structure after five recycles.
