Summary: The photocatalytic activity of NiCoPrFe2O4 and Cd-NiCoPrFe2O4 synthesized by the self-ignition sol-gel process was investigated in this study. NiCoPrFe2O4@CNTs was prepared via ultrasonication approach. Methyl violet was used as a dye to examine the photodegradation activities of the synthesized photocatalysts under visible light. XRD confirmed the spinel crystalline structure, and the morphology of the samples was observed through scanning electron microscopy. NiCoPrFe2O4, Cd-NiCoPrFe2O4, and NiCoPrFe2O4@CNTs showed percentages of degradation of methyl violet of 55.46%, 78.29%, and 85.96% respectively. The photocatalytic performance of the CNT-based nanocomposite was found to be increased due to the enhanced charge separation property of CNT.

Summary: The present study successfully synthesized highly porous TiO2 by incorporating PANI polymer into the sol-gel chemistry of TiO2/TTIP. The TP samples exhibited a porous ginger-like nanostructure with smaller particle size compared to pristine TiO2. XPS analysis confirmed the presence of hydrogen bonds between Ti-OH groups of TiO2 and protonated nitrogen of PANI. UV-visible absorption study showed a small shift in absorption wavelength for TP8 sample and a reduction in Eg value. FTIR results confirmed the interaction between PANI and TiO2. The TP8 sample showed high photocatalytic activity towards Methylene blue dye degradation. The study offers an excellent photocatalyst TP8 with 8 wt% of PANI for the degradation of MB dye. Evaluation: 8 points

Summary: This study synthesized a three-dimensional network structure catalyst 3D-rGO/BP/ZnO with the properties of easy separation and recycle, which exhibited synergistic effect between adsorption and photocatalysis. The adsorption experiments showed that the pseudo-second-order kinetic model and Freundlich model were appropriate for describing adsorption behavior. The photocatalytic experiment revealed that 3D-rGO/7-BP/ZnO had the best photocatalytic performance, degrading 93.0% of RhB in 120 min. 3D-rGO/BP/ZnO heterostructure could boost the separation of photogenerated electrons and holes, and superoxide radicals (.O-2) were the main active species. After three catalytic cycles, the photocatalysts exhibited excellent stability. This study offered a fresh perspective on the effective use of photocatalyst in environmental rehabilitation.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.

Summary: In this study, a novel polydopamine-functionalized lignin-containing pulp foam evaporator with high-efficiency desalination and multi-contaminant adsorption capabilities was designed. The foam evaporator showed excellent light absorption, water absorption, thermal conductivity, and chelation abilities, allowing for solar evaporation and contaminant adsorption synergistically. It also exhibited potential applications in metal ion concentration and contaminated seawater treatments, and demonstrated superior biodegradability compared to poly-styrene foam. This foam material holds promise for developing multifunctional photo-thermal systems for solar-driven water purification.
