Tubular nanoreactors, which exhibit a distinctive void-confinement effect, have become intriguing for their prospective applications in catalysis. However, rationally constructing these structures remains formidable challenge, particularly realizing significantly synergistic catalytic enhancement. In this study, we present reliable template polymerization-guided synthetic strategy, creating hollow CoSn(OH)6 cubes inside polydopamine (PDA) nanotubes (CoSn(OH)6@PDA NTs). This sample functions as potent peroxymonosulfate (PMS) activator toxic contaminant oxidation. Diverse reactive oxygen species produced within the enhance efficiency. The exceptional property results from rich active sites of and distinct nanotubular structure, concentrates reactants benefits mass transfer process. research opens possibilities developing high-performance robust catalysts with spatial confinement effects, advancing water treatment technology.

Abstract The development of advanced catalysts frequently employs trial‐and‐error methods and is lack highly controlled synthesis, resulting in unsatisfactory efficiency performance. Here we propose a data‐driven prediction coupled with precise synthesis strategy to accelerate the single‐atom (SACs) for efficient water purification. approach enables rapid screening high‐performance SACs from 43 metals‐N 4 structures comprising transition main group metal elements, followed by validation structural modulation improved performance through controllable hard‐template method. Impressively, well‐designed Fe‐SAC high loading Fe‐pyridine‐N sites (~3.83 wt %) mesoporous structure, exhibits ultra‐high decontamination (rate constant 100.97 min −1 g −2 ), representing best Fenton‐like activities sulfonamide antibiotics date. Furthermore, optimized shows excellent robust environmental resistance cyclic stability almost 100 % degradation 100‐h continuous operation. Density functional theory calculations reveal that can reduce energy barrier intermediate O* formation, rate‐determining step, selective generation singlet oxygen. integration method provides novel paradigm field as well other important fields including sustainable catalysis.

The risk of harmful microorganisms to ecosystems and human health has stimulated exploration singlet oxygen (1O2)-based disinfection. It can be potentially generated via an electrocatalytic process, but is limited by the low production yield unclear intermediate-mediated mechanism. Herein, we designed a two-site catalyst (Fe/Mo–N/C) for selective 1O2 generation. Mo sites enhance generation precursors (H2O2), accompanied intermediate •HO2/•O2–. Fe site facilitates activation H2O2 into •OH, which accelerates •HO2/•O2– 1O2. A possible mechanism promoting through ROS-mediated chain reaction reported. as-developed electrochemical disinfection system kill 1 × 107 CFU mL–1 E. coli within 8 min, leading cell membrane damage DNA degradation. effectively applied medical wastewater.

Dual-atom catalysts (DACs) have shown significant application potential in Fenton-like reactions. However, effectively modulating their electronic structure and fully understanding the mechanisms driving high catalytic activity remain challenging. Herein, we propose a coordination anions dimensionality engineering strategy to synthesize biomass-derived dual-atom FeCo-N4O1C catalysts, which Fe Co atoms are bridged by two-dimensional planar N three-dimensional (3D) axial O atom. Experimental data theoretical calculations reveal that 3D of induces spin state undergo transition from low an intermediate compared with single-atom Fe-N4O1C, resulting moderate adsorption desorption intermediates, thus reducing energy barriers for generating more singlet oxygen high-valent cobalt-oxo species during peroxymonosulfate activation. The electron transfer neighboring through can prevent poisoning active species. Benefiting synergistic effects multiple sites, catalyst-dose normalized reaction rate constant reaches 14.5 L min-1 g-1 under concentrations─an improvement 1 ∼ 2 orders magnitude over most reported catalysts. practical applicability is demonstrated nearly 100% pollutant removal 7 days continuous operation membrane filtration system. This study provides deep insights into relationship between performance spin-state regulation DACs, introduces promising approach large-scale synthesis low-cost, highly efficient DACs
