A porous graphitic biochar wrapped Co9S8 core–shell composite enables pH-universal activation of peroxymonosulfate for highly efficient and rapid antibiotics degradation

Abstract

Herein, the boosted Co(ii) regeneration by various S species along with formed N and O active sites in novel as-prepared Co9S8@N–O–BC facilitated the activation of PMS for efficient SMX degradation through a non-radical pathway.
