Published: Aug. 28, 2024

Abstract Piezocatalytic Fenton (PF) system emerges as a promising approach to wastewater treatment by leveraging piezocatalysis enhance Fenton‐like reactions. However, conventional piezocatalysts encounter challenges because they often compromise catalytic properties in biased favor of superior piezoelectricity, resulting sluggish kinetics. To tackle this trade‐off, here novel class kesterite‐type narrow bandgap piezoelectrics, Cu 2 XSnS 4 (CXTS, X = Zn, Ni, Co), is developed for PF reactions, which exhibit unique combination physicochemical attributes favorable catalysis such (1.2–1.5 eV), high free charge density (1 × 10 18 cm −3 ), mobility, and redox activity while retaining excellent piezoelectricity (62–142 pm V −1 ). With the well‐balanced piezoelectric, semiconducting, properties, CXTS‐based systems demonstrate outstanding performance tetracycline degradation, delivering notable reaction kinetics 0.34 min only with minor H O dosage (1.2 m outperforming most reactions requiring large amount factor up 10. Such remarkable fulfilled simultaneously effective activation situ generation reactive oxygen species from water via piezocatalysis. Additionally, distinctive hierarchical morphology consisting 2D nanosheets enables easy crystal domain deformation trigger piezoelectric effect, thereby drastically reducing mechanical energy input required drive Rigorous testing has validated viability practical feasibility system. The study offers new design strategy highly efficient systems, enabling cost‐effective sustainable approach.

High‐Entropy Layered Double Hydroxides for Efficient Methanol Electrooxidation

Small, Journal Year: 2025, Volume and Issue: 21(11)

Published: Feb. 16, 2025

Abstract The electrocatalytic methanol oxidation reaction (MOR) is considered as an effective method to replace oxygen evolution (OER) for efficient hydrogen production. However, the sluggish kinetics and difficulty of breaking C─H bond Ni‐based catalysts limit further application. Herein, three high‐entropy layered double hydroxides (HELHs), namely ZnNiFeCoV‐HELH, ZnNiFeCoCr‐HELH, ZnNiFeCoAl‐HELH (denoted V‐HELH, Cr‐HELH, Al‐HELH, respectively), are successfully synthesized. Among them, V‐HELH displays lowest potential 1.39 V at 100 mA cm −2 compared Cr‐HELH (1.41 V) Al‐HELH (1.44 V). After five cycles, formate yield maintains over 95% first cycle with excellent stability. Such outstanding performance surpasses that most state‐of‐the‐art MOR reported so far. A series experiments reveal exhibits fastest largest number active Ni 3+ species. Further investigations theoretical calculations prove shows strongest adsorption energy −3.31 eV. introduction vanadium (V) relatively larger tensile strain optimizes d─band center (−0.54 eV) lowers barrier (−1.62 from * CH 3 O 2 O. This work provides new insights rational design electrocatalysts.
