Abstract The sustainable management of water resources is a critical global challenge, with advanced oxidation processes emerging as promising solution for addressing environmental pollution. However, the clear trade‐off between catalytic activity and stability in existing catalysts hinders their broader application. In this study, nanocrystalline/amorphous (N/A) microwire catalyst developed, featuring design that regulates nanocrystal size while preserving pure amorphous matrix. Unlike brittle annealed N/A microwires subjected to structural relaxation, as‐cast demonstrate outstanding performance oxidation. They can completely degrade pollutants within 60 s maintain up 40 reuse cycles. Theoretical calculations material characterizations reveal exceptional properties arise from combined effects residual stresses stored matrix synergistic effect nanocrystals phases. Moreover, optimally sized nanocrystalline phase optimizes atomic arrangement induces an structure low coordination number, providing abundant active sites. This also enhances adsorption characteristics persulfate accelerates electron transfer. These findings offer novel framework developing efficient stable wastewater treatment.

Abstract Single‐atom catalysts (SACs) have garnered significant attention in the applications of environmental remediation based on Fenton‐like systems. Current research single‐atom catalysis often emphasizes catalytic activity and mechanism regulation, while paying limited to simultaneous enhancement both stability—a critical factor for practical scale‐up SACs. This review systematically summarizes recent advances synchronization strategies improving stability catalysis, with a focus design principles mechanisms four key strategies: coordination engineering, confinement effects, carrier substitution, module design. To best knowledge, this represents first comprehensive from perspective concurrent optimization stability. Additionally, auxiliary role machine learning lifecycle assessment (LCA) is evaluated advancing these strategies. By investigating interplay among different support materials, configurations, reaction environments, as well enlarged modules, factors governing stability/activity SACs are highlighted, future directions proposed developing next‐generation high efficiency long‐term durability remediation.

Piezocatalysis, an emerging green and advanced oxidation technology, has recently been widely researched in environmental treatment. However, the limited polarization efficiency of piezocatalyst is a serious bottleneck for its practical application. The search excellent with high piezoelectric coefficient abundant reactive sites remains urgent task that needs to be developed. Herein, piezocatalyst, CaZn2(BO3)2 (CZBO), obtained by quenching piezocatalysis, which exhibited superior activity ibuprofen (IBP) carbamazepine (CBZ) removal 100% 83.8% under ultrasonic cavitation (120 W, 40 kHz) within 36 min, respectively. outstanding piezocatalytic degradation was attributed strong material synergistic effect oxygen vacancies (OVs) lattice distortion, effectively facilitated generation concentration species (ROS). distortion induced O-deficient [BO3] plane units can promote e– h+ pair separation transportation, OVs electron-rich regions significantly decrease O–O bond activation energy, thus collaboratively contributing production ROS IBP CBZ degradation. This work provides simple avenue enhancing based on proposes insights into reaction mechanisms degrading nonantibiotic pharmaceuticals wastewater.
