Abstract—Photoelectrochemical (PEC) degradation and with the help of applied bias upon the solution is that, the
electrodegradation (ED) of methyl orange were investigated in applied bias can prevent carrier charges bination and
aqueous NaCl and Na2SO4 solutions. Photocatalytic extend the lifetime of photogenerated active holes [7,8].
degradation(PCD) was also performed in TiO2(P25) suspension In the set up of a PEC reactor, a working electrode and a
under UV-irradiation parison. Electrodegradation counter electrode monly used with an electrical bias
efficiencies showed enhanced decolorization performance at applied between the two electrodes. Although photocatalyst
higher concentrations of electrolyte solutions and applied
films can be easily removed from the solution after treatment, it
potentials. There is synergetic effect between electrolysis and
photocatalysis treatments. Photocatalytic degradation process could hardly solve the problem of unsatisfied photocatalytic
alone could result in % decolorization of methyl orange pared with photocatalyst particles. In the presen
