Pivotal Role of Multishelled Architecture in Nanoreactor with Spatial Confined Co₃O₄ for Peroxymonosulfate Activation and Contaminants Degradation

Small Structures, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 26, 2025

In recent years, cobalt‐based catalysts have been widely used in advanced oxidation technology to degrade pollutants water environments. However, the reasons for improved efficiency and performance of with different shapes structures on activation persulfate contaminant degradation are still largely unknown. This study constructs catalysts, namely, Co 3 O 4 nanosphere, multishelled nanosphere (MSCONS), nanocube nanocube, combination activation, tetracycline (TC) bisphenol A (BPA), representative substances antibiotics endocrine disruptors Batch experiments exhibit satisfactory TC (96.3%) BPA (98.5%) under MSCONS/peroxymonosulfate. Furthermore, MSCONS exhibits wide applicability complex matrix conditions. Consequently, an integration density functional theory computations intermediates analysis demonstrates that synergy, rather than isolated effects radical nonradical active species, broadens pathways BPA, thereby improving removal efficiency. Overall, this offers novel insights into factors contributing enhanced varying structures. Additionally, it proposes new research avenues investigating other transition metal‐based catalysts.

Nano Cobalt-Loaded Porous Carbon Derived from Waste Plastic for Efficient Persulfate Activation and Tetracycline Degradation

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(5), P. 371 - 371

Published: Feb. 27, 2025

The excessive utilization and emission of waste plastics have caused serious damage to the environment, it is great significance explore high-value methods for these plastics. To address this challenge, functional nano cobalt-loaded porous carbon materials (CoPC) with excellent antibiotic wastewater removal properties were prepared by one-step pyrolysis using PET as a source, process described in paper. Characterization revealed that obtained CoPC-2 catalysts had high degree defects, large specific surface area (343.41 m2/g), an abundant pore structure. Degradation results displayed removed 87.93% 20 mg/L tetracycline reaction rate constant 0.0668 min-1. Moreover, exhibited degradation performance over wide range pH levels (4-10) coexistence multiple inorganic anions. Electron paramagnetic resonance radical quenching experiments radicals (·OH, SO4·-) non-radicals (1O2) pathway participated degradation, non-radical being dominant. This study not only offers promising prospects resource plastics, but also provides novel approaches design nanomaterials treatment.
