Abstract:
Peracetic acid (PAA)-based advanced oxidation processes (AOPs) are appealing for water treatment due to their environmentally benignity and ease of activation. However, the predominant generation of radicals in the existing catalytic systems severely limits their practical water decontamination performance. In this study, we report an Mn-doped Cu2(OH)3Cl catalyst supported on hexagonal boron nitride (Mn-Cu2(OH)3Cl@BN), providing dual reaction centers (DRCs) and abundant oxygen vacancies (OVs) to facilitate selective generation of singlet oxygen (1O2) from PAA activation. The Mn introduction raised the electron density of Cu sites to enhance PAA binding and activation towards 1O2 generation. Additionally, the BN support and the induced OVs further accelerated the electron transfer, rendering the composite catalyst high activity. As a consequence, the Mn-Cu2(OH)3Cl@BN/PAA system exhibited excellent activity for degradation of tetracycline hydrochloride (TCH), with a reaction kinetic constant 91 times higher than that of Cu2(OH)3Cl. In addition, the degradation efficiency was still above 85 % after five runing cycle, indicating its good stability. Our work lays an important basis for innovation of PAA-based AOPs towards low-carbon water treatment application.
