AB  - A novel alkylpolyglycoside (APG)-modified MnFe(2)O(4) nanocomposite 
      (APG@MnFe(2)O(4)) enriched with oxygen vacancies (VOs) was developed via 
      co-precipitation and characterized as a peroxymonosulfate (PMS) activator to 
      degrade 2,4-dichlorophenol (2,4-DCP) as the model contaminant. The APG 
      effectively promoted the in situ formation of VOs on MnFe(2)O(4) and subsequently 
      enhanced the production of singlet oxygen ((1)O(2)). Furthermore, the 
      APG@MnFe(2)O(4) initialized an even more efficient non-radical pathway and 
      dominated the degradation of 2,4-DCP. The constructed APG@MnFe(2)O(4) exhibited a 
      much higher reaction rate constant (0.0522) by ~12.73 times of that of the bare 
      MnFe(2)O(4) (0.0041). The degradation efficiency of 2,4-DCP in the 
      APG@MnFe(2)O(4)/PMS system approached 93% within 90 min, a rate significantly 
      higher than that in the MnFe(2)O(4)/PMS system (32%) given the same condition. 
      The reasonable catalytic mechanism can be attributed to the Fe/Mn/VOs species. 
      The APG@MnFe(2)O(4) also exhibits universally high removal activity for various 
      pollutants and excellent cyclic stability. Thus, the APG@MnFe(2)O(4) is a 
      promising PMS activator, and its utilization offers a useful strategy for 
      developing VOs-enriched MnFe(2)O(4) catalysts as a means of eliminating organic 
      pollutants from wastewater.
