Natural bamboo-derived porous carbon activates PMS for BPA degradation:A singlet oxygen-dominated nonradical pathway
Natural bamboo-derived porous carbon activates PMS for BPA degradation:A singlet oxygen-dominated nonradical pathway
摘要
Bisphenol A(BPA),a widespread endocrine-disrupting compound,necessitates efficient activation of peroxy-monosulfate(PMS)for its degradation.Conventional carbon-based catalysts frequently exhibit limited efficiency,poor stability,and potential environmental risks.Bamboo-derived porous carbon material(BCM)and bamboo-derived porous carbon material loaded with Fe(BCM-Fe)serve as effective catalysts for activating PMS to degrade BPA.The BCM/PMS system achieved a BPA removal efficiency of 94.44％within 150 min,while the BCM-Fe/PMS system attained 97.8％.Quenching experiments and electron paramagnetic resonance(EPR)analysis identified non-radical singlet oxygen(1O2)as the dominant reactive species.Density functional theory(DFT)calculations demonstrated that atomically dispersed Fe species on BCM-Fe significantly enhanced PMS adsorption energy and activation kinetics compared to BCM.Both catalysts exhibited excellent reusability,confirming their potential as practical and sustainable catalysts.This study provides fundamental insights for designing efficient,environmen-tally benign carbon-based catalysts for advanced oxidation processes.
