      visible-light irradiation.

AB  - A plasmonic photocatalyst Ag-AgI supported on mesoporous alumina 
      (Ag-AgI/Al(2)O(3)) was prepared by deposition-precipitation and photoreduction 
      methods. The catalyst showed high and stable photocatalytic activity for the 
      degradation and mineralization of toxic persistent organic pollutants, as 
      demonstrated with 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), and 
      trichlorophenol (TCP) under visible light or simulated solar light irradiation. 
      On the basis of electron spin resonance, cyclic voltammetry analyses under a 
      variety of experimental conditions, two electron transfer processes were verified 
      from the excited Ag NPs to AgI and from 2-CP to the Ag NPs, and the main active 
      species of O(2)(*-) and excited h(+) on Ag NPs were involved in the photoreaction 
      system of Ag-AgI/Al(2)O(3). A plasmon-induced photocatalytic mechanism was 
      proposed. Accordingly, the plasmon-induced electron transfer processes elucidated 
      the photostability of Ag-AgI/Al(2)O(3). This finding indicates that the high 
      photosensitivity of noble metal NPs due to surface plasmon resonance could be 
      applied toward the development of new plasmonic visible-light-sensitive 
      photocatalysts and photovoltaic fuel cells.
