Abstract: [Display omitted] • Mn 3 O 4 /MXene composites with precise control over MXene component were synthesized by a hydrothermal-calcination method. • The introduction of MXene degrades pollutants through a nonradical mechanism by accelerating the electron transfer. • A remarkable and stable catalytic efficiency were achieved by the Mn 3 O 4 /MXene composites. • Excellent cycle stability and anti-interference are displayed in actual water applications. Regulating the performance of manganese oxide catalysts to enhance peroxymonosulfate (PMS) activation for degrading emerging organic pollutants remains a significant challenge. To address this issue, Mn 3 O 4 /MXene composites with precisely controlled MXene contents are synthesized by combining hydrothermal and calcining methods, resulting in a significant regulate the pathway of Mn 3 O 4 activation of PMS and a notable enhancement bisphenol A (BPA) degradation efficiency. The normalized first-order rate constant for optimized Mn 3 O 4 /MXene composites is 0.0218 g/(m2⋅min), which is 8.4 and 2.0 times higher than those of MXene and Mn 3 O 4 , respectively. Moreover, this catalyst exhibits excellent mineralization capacities, achieving up to 88.2 % total organic carbon removal efficiency. Combining with electrochemical and electron paramagnetic resonance analysis, the mechanism of electron transfer processes in this composite is elucidated comprehensively. Moreover, Mn 3 O 4 /MXene displays remarkable efficiency in degrading refractory pollutants, including antibiotics, phenols, and dyes. Furthermore, Mn 3 O 4 /MXene composites exhibit superior stability, reusability, and resistance to interference, highlighting their versatility in diverse environmental contexts. Notably, the catalyst maintains stable catalytic activity for long-term pollutant removal in a continuous-flow system. This study presents a novel approach for developing composite catalysts, providing new avenues for the treatment of emerging pollutants in wastewater. [ABSTRACT FROM AUTHOR]
