“…For this, Cu/Bi LDHs containing CO 3 − as the counter anion were synthesized by a simple co-precipitation method, resulting in a 3D hierarchical flower-like structure. The ZIF-67 linker has decorated the surface of the LDHs resulting in ZIF-67-Cu/Bi-LDHs [ 60 ]. Figure 2 shows a schematic illustration for the formation of the hierarchical flower-like structure of ZIF-67-Cu/Bi LDHs.…”

“…The adsorption capacity was attributed to the special layered structure of the adsorbent in ZIF-67-Cu/Bi-LDHs and strong p-p an interaction between iodine and nitrogen of the imidazole ring of the ZIF67. The adsorption followed the Freundlich model isotherm and pseudo-second-order kinetics [ 60 ]. This material can be very useful for the treatment of nuclear wastewater which is a huge risk to aquatic life and human health [ 60 ].…”

Nanotechnology finds its application almost in every field of science and technology. At the same time, it also helps to find the solution to various environment-related problems, especially water contamination. Nanomaterials have many advantages over conventional materials, such as high surface area, both polar and non-polar chemistries, controlled and size-tunable, easier biodegradation, which made them ideal candidates for water and environmental remediation as well. Herein, applications of non-carbon nanomaterials, such as layered double hydroxides, iron oxide magnetite nanoparticles, nano-polymer composites, metal oxide nanomaterials and nanomembranes/fibers in heavy metal contaminated water and environmental remediation are reviewed. These non-carbon nanomaterials, due to their tunable unique chemistry and small size have greater potentials for water and environmental remediation applications.

“…Layered double hydroxides (LDHs) possess positively charged layers and exchangeable interlayer anions. − Due to the particular compositions and structures, LDHs acting as sorbents have displayed a vast perspective in removing environmental contaminants . Ma et al reported [S x ] 2– -intercalated LDH (MgAl-S x -LDH) and found that interlayered [S x ] 2– reduced I 2 to [I 3 ] − ions which were immobilized within the LDH gallery, realizing a maximum iodine capture ( q m ) of 1520 mg/g .…”

The development of low-cost and high-efficiency iodine sorbents is of great significance for the control of nuclear pollution. In this work, we intercalate the tin sulfide cluster of [Sn2S6]4– to Mg/Al-type layered double hydroxides to obtain Sn2S6-LDH, which exhibits highly efficient capture performance of iodine vapor and iodine in solutions. The dispersion effect of the positively charged LDH layers contributes to the adequate exposure of [Sn2S6]4– anions, providing plentiful adsorption sites. For iodine vapor, Sn2S6-LDH showed an extremely large iodine capture capacity of 2954 mg/g with a large contribution from physisorption. For iodine in solutions, a significantly large sorption capacity of 1308 mg/g was achieved. During iodine capture, I2 molecules were reduced to I– ions (by S2– in [Sn2S6]4–), which then reacted with Sn4+ to form SnI4, where the molar amount of captured iodine is 4-fold that of Sn. Besides, the as-reduced I– combined with I2 again to generate [I3]−, which then entered the LDH interlayers to maintain electric neutrality. While reducing iodine, S2– itself in [Sn2S6]4– was oxidized to S8, which further combined with SnI4 to form a novel compound of SnI4(S8)2. The excellent iodine capture capability endows Sn2S6-LDH with a promising application in trapping radioactive iodine.
