AB  - The heterogeneous Fenton-like reaction (HeFR) has always been a research focus 
      for environmental applications. However, it has long been difficult to reach a 
      consensus on the reaction mechanism because the process of metal ions dissolution 
      and its role were not well understood. In this paper, we propose the courses of 
      organics-mediated coordination or/and reduction dissolution of ferric hydroxide 
      to initiate the autocatalytic kinetics of phenol degradation and illustrate it 
      through density functional theory (DFT) and experiments. With the increase of 
      hydrogen peroxide concentration, the degradation of phenol changes from 
      autocatalytic kinetics to first-order kinetics. Furthermore, a novel "limit 
      segmentation method" initiated by us indicates that homogeneous reaction plays a 
      decisive role in the phenol degradation process. The dominant roles of the 
      reactive organics in both iron dissolution and the iron cycle and of the 
      homogeneous reaction in the whole degradation process in the ferric 
      hydroxide-based HeFR system are brand-new insights that pave the pathway for 
      future research.
