Consumption of contaminated water can have detrimental effects on the health every living organism earth. There is, thus, a need to develop novel materials and technologies purify water. Water is also source hydrogen, clean renewable fuel that be generated through action photoactive catalyst earth's abundant solar energy. Using photocatalysis, we by removing organic pollutants photodegradation reaction (oxidation) produce hydrogen (H2) evolution (reduction). However, combine these two...
Abstract It remains a challenge to design aqueous electrolytes secure the complete reversibility of zinc metal anodes. The concentrated water‐in‐salt electrolytes, e.g., 30 m ZnCl 2 , are promising candidates address challenges Zn anode. However, pure electrolyte fails deliver smooth surface morphology and practically relevant Coulombic efficiency. Herein, it is reported that small concentration vanillin, 5 mg mL water −1 added transforms anode by eliminating dendrites, lowering Hammett...
Abstract Here, four MOFs, namely Sc-TBAPy, Al-TBAPy, Y-TBAPy, and Fe-TBAPy (TBAPy: 1,3,6,8-tetrakis( p -benzoic acid)pyrene), were characterized evaluated for their ability to remediate glyphosate (GP) from water. Among these materials, Sc-TBAPy demonstrates superior performance in both the adsorption degradation of GP. Upon light irradiation 5 min, completely degrades 100% GP a 1.5 mM aqueous solution. Femtosecond transient absorption spectroscopy reveals that exhibits enhanced charge...
Abstract Plating battery electrodes typically deliver higher specific capacity values than insertion or conversion because the ion charge carriers represent sole electrode active mass, and a host is unnecessary. However, reversible plating are rare for electronically insulating nonmetals. Now, highly iodine cathode presented that operates on redox couples of I 2 /[ZnI x (OH ) 4− ] 2− in water‐in‐salt electrolyte. The with theoretical 211 mAh g −1 plates carbon fiber paper as current...
Dual-ion batteries that use anions and cations as charge carriers represent a promising energy-storage technology. However, an uncharted area is to explore transition metals electrodes host carbonate in conversion reactions. Here we report the reversible reaction from copper Cu2 CO3 (OH)2 , where electrode comprising K2 KOH solid self-sufficient with anion-charge carriers. This dissociates associates K+ ions during battery discharge. The active mass anion-bearing cathode exhibit capacity of...
Herein, we report the synthesis of photoactive polymeric organo-sulfur (POS) materials. These polymers absorb light in ultraviolet/visible and near-infrared region solar spectrum, upon irradiation, they reduce water to hydrogen (H2 ). The decoration POS materials with nitrile (-CN) groups is found be critical factor for enhanced interactions co-catalyst, Ni2 P, leading greater H2 evolution rates compared nitrile-free material.
Using elemental selenium as an electrode, the redox-active Cu2+/Cu+ ion is reversibly hosted via sequential conversion reactions of Se → CuSe Cu3Se2 Cu2Se. The four-electron redox process from to Cu2Se produces a high initial specific capacity 1233 mA h g-1 based on mass alone or 472 Cu2Se, fully discharged product.

Fluoride is a promising charge carrier for batteries due to its high charge/mass ratio and small radius. Here, we report commercial copper powder exhibits reversible capacity of up 222 mA h g-1 in saturated electrolyte 16 m KF. This suppresses dissolution CuF2, the charged product. Furthermore, KF solid comprised Cu electrode facilitates initial capacity. Our results showcase potential aqueous fluoride using as an electrode.
The impact of metals within a family isostructural metal-organic frameworks (MOFs) on the adsorption and photodegradation herbicide glyphosate (GP) is presented in this study.

Zn Metal Batteries Designing effective aqueous electrolytes for zinc metal anodes remains a challenge. In article number 2301712, P. Alex Greaney, Xiulei Ji and co-workers show that adding few ppm vanillin to 30 m ZnCl2 enhances the anode's reversibility, prevents dendrite formation, boosts Coulombic efficiency. This electrolyte results in battery with an N/P ratio of 2 retains stable cycling over 800 cycles.
