Cobalt-based metal–organic framework (MOFs)-derived catalysts are acknowledged for their effectiveness in activating peroxymonosulfate (PMS) the treatment of persistent pollutants. However, limited adsorption PMS on catalyst surface markedly reduces its degradation efficiency. To overcome this limitation, nanoflower-like Eu2O3/Co3O4-0.3 were successfully fabricated by incorporating europium (Eu) into cobalt-based MOF via hydrothermal and calcination techniques. The doping Eu not only enhances more catalyst's but also serves as an electron transfer mediator to regulate Co2+/Co3+ redox cycle promote generation oxygen vacancies (OV). was used activate rhodamine B (RhB), it found that rate constant (k) Eu2O3/Co3O4-0.3/PMS system approximately 8 times higher than Co3O4/PMS system, achieving complete within 20 min. Furthermore, exhibited excellent mineralization capacity, stability, recyclability. Trapping experiments indicated singlet (1O2) is primary active species, suggesting material applicable complex aqueous environments. Density Functional Theory (DFT) calculations revealed energy (Eads) Eu2O3 −4.05 eV, which much greater Co3O4 (Eads = −0.32 eV). This study provides a new method designing nonhomogeneous efficient
