Summary: This Perspective highlights the pathways to prepare porous ionic liquids using easily accessible materials for reduced environmental impact. The study demonstrates that suspensions of porous solids are stable in eutectic mixtures, which indicates their potential in preparing porous ionic liquids. Porous ionic liquids maintain the wide electrochemical window observed in their precursor pure ionic liquids, making them suitable for green electrochemical reactions, especially those involving gases with enhanced solubility in the porous suspensions. Furthermore, their capacity as gas-rich media suggests potential sustainable biomedical and pharmaceutical applications, provided that non-toxic, biocompatible ionic liquids and porous solids are utilized.

Summary: Ion adsorption inside electrified carbon micropores is crucial for supercapacitor operation, with transition-metal cations forming oligomer species when confined in negatively charged micropores. These oligomers exhibit sluggish dissociation kinetics, leading to capacitance fading, but can be dissolved by applying a positive potential. An intermittent reverse cycling strategy is proposed to periodically evacuate micropores and revivify capacitance.

Summary: In this study, we investigate the influence of ionic correlations on the reaction rates and selectivity of CO2 electroreduction. Through experiments, we find that at intermediate concentrations, the reduction rates of CO2 are accelerated and the efficiency of CO production is enhanced. The acceleration of CO2 reduction is due to the amplification of potential-dependent driving forces, rather than changes in onset potential. These findings are applicable to both cocatalytic and noncatalytic ions.

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: Mixed-metal chalcohalide semiconductors, specifically Pb2SbS2I3 and Pb2BiS2I3, were synthesized in solution phase using readily available precursors. The reaction parameters were fine-tuned to produce rod-like structures with tunable dimensions. The quaternary chalcohalides exhibited photoluminescence both as an ensemble and at the single particle level, as observed through fluorescence microscopy. Electronic structure calculations were used to evaluate the stability and band gap of Pb2SbS2I3 polymorphs and their coloring patterns. These synthetic methods pave the way for further exploration of complex chalcohalides and other multinary semiconductors for new technological applications.
