| 英文摘要 | Bisphenol A (BPA), a persistent endocrine disruptor, poses critical water treatment challenges. In this study, cubic catalysts dominated by {100} crystal facets (i@Co@CeO2 CNs) were synthesized via crystal surface engineering combined with a cobalt (Co) impregnation strategy. This approach aimed to enhance activation of peroxymonosulfate (PMS) for the degradation of BPA by modulating the exposed crystal facets of cerium dioxide (CeO2) carriers. The {100} facets exhibited enhanced oxygen vacancies (Ov) (O beta: 29.57 %) and Co dispersion (0.58 at%), achieving 93 % BPA removal within 120 min (k = -0.0184 min-1)-15.3 x faster than {111}-faceted systems. The system maintained > 85 % efficiency across pH 2-10 and resisted anion interference (Cl-/SO42-), retaining > 80 % activity. Radical quenching and EPR identified center dot OH, SO4center dot-, and O2center dot- as dominant oxidants (>75.2 % contribution). DFT calculations revealed strong PMS chemisorption (Eads = -3.17 eV) on {100} facets, enabling targeted electron injection into O-O sigma* orbitals that weakened O-O bonds (lowest cleavage barrier: 1.01 eV). Toxicity assessment confirmed intermediates had orders-of-magnitude lower acute toxicity than BPA, with progressive mineralization (40.6 % TOC removal in 120 min) to CO2/H2O. This work demonstrates crystal facet engineering as a novel strategy for designing eco-efficient water remediation catalysts. |
