      Abstract:

      The working   mechanism of a ceria-supported Cu (Cuat:Ceat=1:10)   system in the Catalytic Wet Oxidation (CWO) of   phenol with O2  (TR,   130–170 C;  PO2,   7 atm) has been thoroughly assessed. Basic relationships amongst   pH, extent of leaching and rate of phenol and TOC   conversion prove the major contribution of a homogeneous   catalytic path by Cu ions on the peculiar CWO pattern of   supported copper catalyst. In addition, gas-phase   reduction/oxidation tests signal the lack of reversibility of the   redox cycle of the CuCeOx  system under typical   reaction   conditions.
