Abstract With the wide application of portable electronic devices, zinc–ion hybrid supercapacitors (ZIHCs) have aroused great interest. However, balancing low‐temperature performance and high energy density ZIHCs remains a huge challenge. Herein, zwitterionic hydrogel electrolyte (ZHE) loaded with carboxymethylcellulose MXene is designed for ZIHCs, which shows excellent frost resistance output voltage. Carboxymethylcellulose enhance flexibility conductivity electrolyte. Moreover, When ZnCl 2 introduced into gel electrolyte, it induces an increase in rate ion transport, enables broadening operating temperature (−40 °C–25 °C). As result, Zn//AC based on ZHE show voltage window V, (specific capacity) 137 Wh kg −1 (247 F g ), potential wearable devices. This study will provide effective strategy design windows, density, practicality.

Fluorescence sensors derived from inorganic fluorescent molecules have attracted enormous attention due to their easy processing and the tunability of chemical properties. However, fluorescence quenching mechanism π-electron density solution pH has been less explored. Covalently tuned graphene quantum dots (GQDs) with quantum-confined electrons efficiently detect 2,4,6-trinitrophenol (TNP) explosives. Herein, GQDs various sizes were designed by using a bottom-up synthesis approach. The was established analysis functional theory (DFT) calculations. During sensing, smaller blue fluorescent-GQDs photoluminescence (PL) emission at 475 nm upon 410 excitation effectively quenched TNP, showing sensitivity selectivity in 14.56 μM range. In contrast, higher density, i.e., G-GQDs, Y-GQDs, O-GQDs, did not show significant phenomena. DFT studies showed that accessible band gap TNP B-GQDs, excited LUMO got transferred thermodynamically driven force, highest observed neutral 7.

Recent Advances of Metal–Organic Framework for Heavy Metal Ions Adsorption

Langmuir, Год журнала: 2024, Номер unknown

Опубликована: Авг. 13, 2024

Heavy metal ion wastewater is a pressing and inescapable issue that closely related to human health ecological security due its toxicity, carcinogenicity, the unmanageable property of this type wastewater. Metal–Organic Frameworks (MOFs) are class crystalline nanoporous materials with flexible designability controllability, showing great potential in field adsorption purification heavy metals In Perspective, we first discuss harm different ions briefly expound virtues MOFs for pollutant adsorption. Then, mainly summarize recent advances construction metal-based (Zr-based, Zn-based, Co-based, Al-based, etc.) their research progress Furthermore, various types MOF additives can often be effectively applied by functional modification or other composition. Additionally, several commonly used kinetics isotherm models also detailed help an in-depth understanding mechanism. Finally, challenges opportunities additionally discussed, review may provide new insight water applications.
