Abstract Metal‐based LDHs incorporated with TMDs, exhibiting excellent synergistic effects, have attracted significant interest from researchers for energy production and storage applications due to their outstanding properties. In the present research, manganese cobalt sulfide into a layered double hydroxide (MnCo 2 S 4 @MnCo LDH) composite has been developed supercapacitors overall water splitting. At current density of 1 mA cm −2 , MnCo LDH–NF exhibits highest specific capacitance (475.8 F g −1 ) compared other electrodes. The LDH//AC ASCD demonstrates an 5.27 Wh kg power 851.06 W along high cyclic stability, retaining 93.75% its 98.36% Coulombic efficiency. Furthermore, shows lower overpotentials (ƞ 10 Tafel slopes HER (–163.9 mV 96.2 dec OER (–150.68 50.95 control fabricated water‐splitting cell LDH (+, −) efficiently generates both oxygen (O hydrogen (H bubbles at low voltage 1.38 V. These results demonstrate that is candidate (supercapacitor) green (water splitting), showing potential future renewable systems.

Study on the Adsorption Mechanism of Cu²⁺ by ZnAl-LDH-Containing Exchangeable Interlayer Chloride Ions

Langmuir, Год журнала: 2024, Номер 40(45), С. 23754 - 23765

Опубликована: Окт. 30, 2024

Different Zn/Al ratios of Cl– intercalated ZnAl-layered double hydroxide (ZnAl-LDH) were prepared using the coprecipitation method, and their adsorption performance for Cu2+ in aqueous solution was evaluated. The factors affecting properties, such as dosage, reaction time, pH, determined by experiments. Then, kinetics isotherm models fitted to evaluate mechanism. results show that ratio has a great influence on effect, best effect is obtained when 4:1, maximum capacity 213 mg/g. mechanism study shows ZnAl-LDH mainly an isomorphic substitution. Additionally, during CuSO4, presence SO42– undergoes interlayer anion exchange with Cl–, process entering facilitates substitution Zn2+. X-ray diffraction (XRD) analysis increases, spacing crystallinity decreases. conforms pseudo-second-order kinetic Langmuir model. Therefore, type monolayer chemical adsorption. thermodynamic indicate spontaneous endothermic process. research revealed adsorbing Cu2+, providing ideas removing recovering copper-containing electroplating wastewater.
