Summary: The rationalization of the ionic covalent organic framework (iCOF) has been demonstrated to satisfy the requirements of high-performance photothermal materials in light harvesting, light-to-heat conversion, and water activation. A new iCOF STTP was constructed through Schiff base chemistry using a hydrophilic dye molecule as the ionic building block. The integrated dye-related ionic moieties greatly enhance light absorbance and improve the efficiency of solar water evaporation.

Summary: Au nanoparticles supported on TiO2 nanotubes were synthesized by a novel vapor phase impregnation approach and their photocatalytic performance in the decoloration of malachite green dye was evaluated. Characterization techniques revealed that the Au nanoparticles exhibited high dispersion and electronic interaction with TiO2, resulting in a decreased band gap energy and surface plasmonic resonance. These findings provide important insights for the application of photocatalytic materials.

Summary: The use of ionic liquid and organic salts as additives for electrolyte systems in dye-sensitized solar cells have been widely studied. The tunability of their physical-chemical properties contributes toward their high efficiencies. In this study, several iodide-based organic salts were tested and compared for their photovoltaic parameters. It was found that 1-ethyl-2,3-dimethylimidazolium iodide ([C2DMIM]I) showed the best efficiency. Furthermore, the performance was further improved by incorporating other compounds, and [C2DMIM]I demonstrated the highest synergy. The effects of the additives were analyzed using electrochemical impedance spectroscopy, and properties related to polarity were found to be consistent with the counter-electrode resistance.

Summary: Pulsed discharge plasma generated in a gas/liquid environment has attracted attention due to its low energy requirements and generation of highly reactive radical species. This study implemented a slug flow system to produce gas/liquid discharge plasma under pressurized argon, and investigated the effect of pressure on the system. The results showed that as the system pressure increased, the decomposition rate of methylene blue decreased and the concentration of total oxidation species increased.

Summary: This study reports a method utilizing dielectric barrier discharge (DBD) for the removal of H2S from natural gas. Compared to the non-coated DBD, the DBD with a coating of ZIF-67 exhibits higher electric field and electron energy, resulting in a high H2S conversion rate of 75.4%, while the conversion rate of methane is low and no conversions of other low alkanes are detected. This provides a potential approach for H2S removal from natural gas sources in remote or isolated regions.

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.
