The performance optimization of isolated atomically dispersed metal active sites is critical but challenging. Here, TiO2@Fe species-N-C catalysts with Fe atomic clusters (ACs) and satellite Fe-N4 were fabricated to initiate peroxymonosulfate (PMS) oxidation reaction. AC-induced charge redistribution single atoms (SAs) was verified, thus strengthening the interaction between SAs PMS. In detail, incorporation ACs optimized HSO5- SO5·- desorption steps, accelerating reaction progress. As a result, Vis/TiFeAS/PMS system rapidly eliminated 90.81% 45 mg/L tetracycline (TC) in 10 min. process characterization suggested that PMS as an electron donor would transfer species TiFeAS, generating 1O2. Subsequently, hVB+ can induce generation electron-deficient species, promoting circulation. This work provides strategy construct multiple atom assembly-enabled composite for high-efficiency PMS-based advanced processes (AOPs).

Water treatment is crucial to improve the water quality and reduce diarrheal chronological diseases caused by excessive discharge of organic dyes other waste. The development expansion efficient catalysts for degradation sterilization has attracted widespread attention. Herein, we report an example a porphyrin-based two-dimensional layered metal-organic framework (MOF) (2DZnTcpp) its sono-/photocatalytic bactericidal activity. dislocated layers effectively avoid close π-π stacking provide porous space oxygen/water/dye contact. introduction Zn ions increases spin orbital coupling through heavy atom effect promotes intersystem crossing process singlet oxygen generation. effective ligand-to-metal charge transfer open catalytic sites also facilitate splitting hydroxyl radical These features together promote reactive species (ROS) generation 2DZnTcpp under light illumination or ultrasound sonication. It worth noting that with high specific surface area porosity shows dye Moreover, could largely inactivate Escherichia coli irradiation (the power 1 sun) sonication 30 min efficiencies over 99.99999%. This work provides approach design synthesis MOF-based sono-/photocatalysts used in purification textile wastewater committed establishment more efficient, fast, environmentally friendly system.
