Summary: Photocatalytic reduction of soluble hexavalent uranium to insoluble tetravalent uranium is a promising strategy for uranium-containing wastewater treatment. However, traditional methods require anaerobic conditions and/or sacrificial agents, leading to increased costs and secondary pollution. This study presents a novel O, K co-doped g-C3N4 photocatalyst that can efficiently remove U(VI) without sacrificial agents under air atmosphere. The synthesized OKDCN photocatalyst showed excellent performance in U(VI) reduction and demonstrated superior reusability and selectivity.

Summary: 30% FeCN/ZIS composite with high photocatalytic activity for chromium-containing wastewater treatment was synthesized through in-situ growth of well-dispersed ZnIn2S4 nanosheets on the Fe doped g-C3N4 surface. The optimized 30% FeCN/ZIS exhibited significantly enhanced photoreduction of Cr(VI) compared to pure ZnIn2S4 and 30% FeCN, thanks to the intense synergy between the Fe-Nx bond and close interface contact, which facilitated high-speed charge transfer and improved optical carrier separation efficiency. Additionally, iron doping narrowed the bandgap of g-C3N4 and prevented electron-hole pair recombination, as confirmed by UV-vis diffuse reflection spectra and photoluminescence spectroscopy.

Summary: The effect of Cr(VI) and TC on the photocatalytic reduction of U(VI) by MoS2/g-C3N4 was investigated. The presence of TC and Cr(VI) improved the photoreduction of U(VI), while their own photocatalytic removal was not significantly influenced. The re-oxidation of U(VI) into U(VI) was observed under increasing irradiation.

Summary: In this study, a photoelectrocatalytic method using a g-C3N4/Sn3O4/Ni (CSN) electrode was proposed for efficient removal of U(VI) from uranium-containing wastewater under visible LED light irradiation. The removal rate of U(VI) reached 94.28% at pH 5.0, significantly higher than the rates achieved by photocatalytic and electrochemical extraction approaches. The excellent photoelectrocatalytic performance of the CSN electrode was attributed to enhanced visible light absorption, promoted separation of electron-hole pairs, and decreased band gap.

Summary: In this study, a novel g-C3N4 filled, phosphoric-crosslinked chitosan gel bead (P-CS@CN) was developed for the adsorption of U(VI) from water. The introduction of more functional groups improved the separation performance of chitosan. At pH 5 and 298 K, the adsorption efficiency and capacity reached 98.0% and 416.7 mg g-1, respectively. The P-CS@CN gel bead exhibited excellent applicability in water based on dynamic adsorption experiments. Thermodynamic analyses showed that the adsorption process of U(VI) on P-CS@CN was spontaneous and endothermic.

Summary: A novel nanoscale zero-valent iron/molybdenum disulfide (nZVI/MoS2) composite was synthesized and applied for the removal of U(VI) from water solutions. The nZVI/MoS2 composites exhibited a high surface area, uniform distribution of nZVI, and higher adsorption capacities than MoS2 due to the synergistic effect. The removal of U(VI) on nZVI/MoS2 involved cation exchange and inner-sphere surface complexation and was enhanced by the complexation of U(VI) with various oxygenated functional groups and subsequent reduction to U(IV) by Fe(0) and/or Fe(II).

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
