Chalcogenide-containing materials are important for the semiconductor and thermoelectric industries and are up-and-coming materials for superconductors, catalysis, and battery applications. Challenges in the synthesis of those materials emerge from the chalcogen’s volatility and from the tendencies of chalcogenide materials to react with even trace quantities of oxygen. Nonetheless, many techniques have been applied to the growth of chalcogenide single crystals, which are convenient for structure determinations and intrinsic property measurements. In the current perspective, we highlight flux crystal growth, solution syntheses, and a novel approach, single-crystal-to-single-crystal modifications, as convenient routes for the preparation of single-crystal chalcogenide materials and emphasize recent advances in those synthetic techniques that have resulted in novel chalcogenide materials classes and that exhibit important properties.

“…The main problem that is associated with the synthetic dyes are their consecutive rate loss during the manufacturing process when used by industries at large scale that further be unconfined into various waterways such as rivers and lakes without their treatment (Periyasamy and Militky, 2020). On the other hand, the removal of heavy metal ions such as Pb (II), Cd (II), Co (II), Zn (II) and Uranium (VI) have also seized a lot of consideration and stroked the thrust from various scientists and researchers due to their proposed treatment methods (Kolodynska et al, 2017;Baldermann et al, 2021;Kameda et al, 2008;Zeng et al, 2022). The nuclear energy plays a vital role in progress of any country's economy.…”

The objective of the present work is to fabricate environment-friendly biosorbent semi-Interpenetrating Network Device based on Psyllium-Okra hybrid backbone and acrylamide by using citric acid and ammonium persulphate as the crosslinker and initiator respectively. Response Surface Methodology (RSM) was used for the optimization of different reaction parameters that sequentially maximized the percentage swelling of the fabricated gel. Amalgamation of acrylamide chains onto Psyllium-Okra based hybrid backbone functional groups present and crosslinking between the different polymeric chains were further confirmed through techniques like FTIR, SEM-EDX and PXRD. The sample showed better thermal stability with decomposition of different phases at higher temperatures. The synthesized semi-IPN was successfully proved to be the proficient candidate for the removal of cationic toxic malachite green dye (62.38 %) with an adsorbent dose of 1.0 g, initial concentration of 10 mg L-1 and time interval of five minute at ambient temperature. Langmuir and Freundlich adsorption isotherm models were studied in order to determine the nature of adsorption took place and it was analysed that Langmuir adsorption isotherm was the best fit model for the removal of toxic cationic malachite green dye. Kinetic studies for the sorption of dyes favoured the reaction mechanism to occur via a pseudo second order pathway with R2 value about 0.99. The synthesized semi-IPN was also utilized in uranium (VI) uptake with an adsorbent dose of 1.0 g, initial concentration of 100 ppb, time interval of 55 minutes at room temperature. The semi-IPN could uptake 97.10 ppb uranium (VI) and was observed highly efficient in uranium (VI) ions removal from aqueous medium. Thus, adsorption studies indicated that semi-IPN prepared out of natural blend was found effective in the sequestration of toxic dyes and heavy metal ions.

“…Materials that can effectively extract and bind uranium will soon be needed to achieve advanced uranium recovery and may even enable future possible uranium extraction from seawater. The oceans contain 3.3 ppb of uranium and thus hold 1000 times more uranium than is recoverable from mining. − Consequently, the development of advanced uranium sorbents is a growing research field that targets uranium recovery and has led already to an impressive diversity of sorbents that include functionalized polymers and silica, porous materials, such as metal–organic frameworks and zeolites, as well as ion-exchange materials. − Recently, layered chalcogenide-based ion-exchange materials have demonstrated great potential for uranium recovery due to their fast kinetics, unprecedented uranium exchange capacity, and overall extremely strong affinity between uranyl ions and the chalcogenide layers. − Layered materials can undergo structural transformations during ion intercalation/deintercalation often upon high cation uptake, while three-dimensional chalcogenide ion-exchange materials can avoid this due to having a rigid framework structure and likely providing selective cavities for trapping radioactive species. , Open-framework chalcogenides, consisting of clusters connected through metal or chalcogen bridges creating pores that are typically occupied by organic cations, are therefore attractive. − Such open chalcogenide frameworks received attention recently as their combination of porosity and chalcogenide-based clusters make them attractive as potential materials for applications in photocatalysis, photoluminescence, X-ray detection, ionic conductors, and semiconductors. − To date, investigations of open-framework chalcogenide materials for their ion-exchange properties are limited to several reports focusing on Cs + and heavy metal (Cd 2+ , Hg 2+ , and Pb 2+ ) ion exchange; ,,− interestingly, the direct synthesis of an all-inorganic open-framework chalcogenide and its use for uranyl ion exchange have not yet been explored.…”

All-Inorganic Open-Framework Chalcogenides, A₃Ga₅S₉·xH₂O (A = Rb and Cs), Exhibiting Ultrafast Uranyl Remediation and Illustrating a Novel Post-Synthetic Preparation of Open-Framework Oxychalcogenides

Fast and effective uranyl sequestration is of interest to the nuclear industry. Recently, layered chalcogenide materials have demonstrated fast, selective, and efficient sorption properties toward uranyl cations, and the development and investigation of new types of chalcogenide materials continues to be of interest and represents an intriguing option for uranyl remediation. Three new all-inorganic A 3 Ga 5 S 9 •xH 2 O (A = Rb, Rb/Cs, and Cs) open-framework chalcogenides were obtained via an in situ alkali carbonate to alkali sulfide conversion process achieved under mild hydrothermal conditions. The structures of the all-inorganic openframework chalcogenides consist of a twofold interpenetrated diamond-like 3D framework containing pseudo-T 3 [Ga 10 S 20 ] 10− supertetrahedra. Forty-eight percent of the structural volume is occupied by A + cations and water species, as established by single-crystal X-ray diffraction (SCXRD), infrared (IR) spectroscopy, and energy-dispersive spectroscopy (EDS). The dynamic nature of the A + cations and water molecules within the pores was investigated via SCXRD as well as by IR spectroscopy-monitored H 2 O-to-D 2 O exchange experiments. Framework stability was probed with post-synthetic treatment of A 3 Ga 5 S 9 •xH 2 O (A = Rb and Cs) samples in acidic solutions that resulted in the formation of the oxysulfide (A/H) 3 Ga 5 S 9−y O y •xH 2 O (A = Rb and Cs; y = 0−1), as shown by SCXRD and IR. Ion-exchange studies on A 3 Ga 5 S 9 •xH 2 O (A = Rb and Cs) samples were carried out utilizing a uranyl acetate solution. The presence of the UO 2 2+ species in the ion-exchange product was supported by IR spectroscopy and EDS. Batch method ion-exchange experiments on Cs 3 Ga 5 S 9 •xH 2 O powder demonstrated fast kinetics with 95% uranyl removal from the uranyl acetate solution during the first minute, a maximum uranyl uptake capacity of 15 mg/g, and the subsequent elution of uranyl species with KCl solution. The porous and dynamic nature of the A 3 Ga 5 S 9 •xH 2 O framework coupled with effective UO 2 2+ •••S 2− bonding interactions makes it a good potential sorbent for uranyl remediation from aqueous media.
