Summary: As the applications of nuclear technology expand, the development of adsorbents with high selectivity and adsorption capacity for removing Uranium (U) from water is crucial. This study used zeolitic imidazolate framework-67 (ZIF-67) to investigate the removal of U from simulated and actual alkaline leach liquor, considering the influence of pH and adsorbent dose. ZIF-67 demonstrated a significant U uptake capacity (396 mg g-1) and excellent removal efficiency for U in both synthetic and alkaline leach liquor (>98% and 97.4%, respectively). A detailed U adsorption mechanism was established based on various characterization techniques, and the alkaline leach liquor was comprehensively characterized with both pre- and post-U adsorption parameters determined. The ZIF-67 adsorbent exhibited satisfactory regeneration performance and structural integrity, with over 80% U removal after the 5th regeneration cycle. Additionally, a first principle-based pore diffusion-adsorption model was employed to predict the adsorption kinetics and related mass transfer parameters.

Summary: A kind of magnetic ferric oxide/polyvinyl alcohol/calcium alginate/UiO-67 (Fe3O4/PVA/CA/UiO-67) nanospheres with homogeneous surface interconnecting structures were successfully prepared in this study. The properties and adsorption capability of the magnetic nanospheres for methylene blue (MB) were investigated. The results showed that the optimum adsorption temperature and pH for MB by the magnetic nanospheres were 298 K and 10, respectively, with a maximum removal of 1371.8 mg/g. The adsorption process followed a pseudo-first-order kinetic model and was confirmed to be exothermic and spontaneous. The interaction mechanism between MB and the magnetic nanospheres was determined to involve hydrogen bond, pi-pi bond, electrostatic interaction, and mesoporous pore flow.

Summary: Three types of ZIF-8 were synthesized using different solvents, with ZIF-8(NH3.H2O) showing the largest adsorption capacity. An increase in the hydrolysis degree of HPAM positively influenced the adsorption capacity of ZIF-8(NH3.H2O). The adsorption capacity of ZIF-8(NH3.H2O) first increased and then decreased with the increase of NaCl concentration in the solution.

Summary: Arsenic (As(V))-contaminated water is a global threat to human health and the ecosystem due to its toxicity, carcinogenicity, and high distribution in water streams. A new ferrocene-encapsulated zeolitic imidazolate framework-67 (Fc-ZIF-67) material was synthesized for efficient As(V) removal from aqueous solutions at neutral pH. The Fc-ZIF-67 adsorbent showed superior As(V) adsorption performance with an adsorption capacity of 63.29 mg/g at neutral pH. The Langmuir and Freundlich isotherm models were used to analyze the adsorption behavior.

Summary: In this study, a highly efficient heterogeneous catalyst was prepared by loading Pt ions on MIL-88 modified with trimethoxy[3-(phenylamino)-propyl]silane for the hydrosilylation reaction. The resulting catalyst showed high catalytic activity and excellent stability, attributed to the pyrrolic nitrogen structure between TPA-MIL-88 and the Pt ion. In addition, 1.2%Pt/TPA-MIL-88 exhibited the highest catalytic activity and could be reused five times without significant deactivation. Importantly, it also achieved satisfactory results for the hydrosilylation reaction of other olefins, implying great potential for application in the silicone industry.

Summary: This study developed a simple and environmentally friendly method to synthesize a natural aromatic-derived plasticizer with excellent plasticization, UV-shielding, and thermostability for PVC. The performance of the plasticized PVC was highly dependent on the number of methylethoxy units in the plasticizer. PVC plasticized by the plasticizer with maximum methylethoxy units showed superior properties compared to PVC blended with toxic dioctyl phthalate (DOP), suggesting it can be an attractive alternative to replace DOP completely.

Summary: The efficient hydrogen evolution reaction (HER) relies on the accessibility of photogenerated charge transfer channels and the activity of catalytic reaction sites. In this study, a 3D porous N-doped Ti3C2Tx MXene matrix was used to confine Cd0.5Zn0.5S nanoparticles (N-TCT@CZS), forming a stable heterojunction with excellent photocatalytic HER activity. The N dopants induced unsaturated structures and increased active sites, while the 3D N-TCT MXene matrix promoted charge transfer kinetics. The Cd-N bonds between N-TCT MXene and CZS enhanced interfacial interaction and expedited interfacial charge transfer, significantly boosting photocatalytic hydrogen evolution.
