Heterogeneous activation of peroxymonosulfate by amorphous boron for degradation of bisphenol S

• Amorphous boron exhibited outstanding catalytic activity and superior stability for peroxymonosulfate activation.
• Effective degradation of bisphenol S was achieved in the amorphous boron/peroxymonosulfate oxidative system.
• The corresponding catalytic oxidation mechanism was elucidated.
