Nitrogen-doped biochar as peroxymonosulfate activator to degrade 2,4-dichlorophenol: Preparation, properties and structure-activity relationship

Yang Jingjing et al.

Summary: Nitrogen-doped biochar (NCMs) have shown potential as metal-free catalysts for persulfates, with conductivity and graphitic N being key properties in determining the degradation efficiency of 2,4-dichlorophenol. The positive effect of conductivity is attributed to the mediated electron-transfer mechanism, while graphitic N serves as the main active site for PMS activation. Understanding the evolution of NCMs' properties with preparation conditions and their correlations with reactivity is meaningful for preparing nitrogen-doped biochar and developing high-performance carbonaceous materials for persulfates-based AOPs.
