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.

ABSTRACT The inability to recycle Fenton reagents and a narrow pH range restricts hematite (Fe 2 O 3 ) application in the actual photo‐Fenton system. engineering of surface structures is identified as an effective approach for enhancing activity material. In this work, three different morphologies (nanosheet, cube, ring) Fe materials containing oxygen vacancies (OVs) were synthesized by hydrothermal method, novel system degradation sulfamethazine was examined. presence oxalic acid, /oxalic acid heterogeneous catalytic demonstrated situ generation H facilitated Fenton‐like reactions. as‐prepared nanosheet‐Fe showed highest efficiency. free radical capture experiment investigated using sacrificial agents, results suggested that superoxide radicals principal active species involved. Ecotoxicity assessments utilizing toxicity prediction software assessed reaction intermediates generated during via quantitative structure–activity relationship indicating these exhibited reduced developmental toxicity. possible pathways mechanism synergistic effect between proposed. This research presents strategy design synthesis photocatalysts with various vacancies, suitable catalysis related environmental contexts.
