Photoelectrochemical (PEC) degradation and electrodegradation (ED) of methyl orange were investigated in aqueous NaCl and Na2SO4 solutions. Photocatalytic degradation(PCD) was also performed in TiO2(P25) suspension under UV-irradiation for comparison. Electrodegradation efficiencies showed enhanced decolorization performance at higher concentrations of electrolyte solutions and applied potentials...
The photocatalytic oxidation of methyl orange (MO) on commercial TiO2 nano-particles could be successfully enhanced by simple mechanical mixing with Fe3+ modified ZSM-5 zeolites (FeZSM-5). When a mixture of TiO2 and FeZSM-5 (TiO2:FeZSM-5 ratio=1:5) was added into the solution, methyl orange removal rate was 58.9% after 30 min of irradiation, which increased 22% compared with using TiO2 alone. However,...
Photoelectrocatalytic (PEC) degradation and electrodegradation (ED) of methyl orange were investigated in aqueous NaCl, NaHCO3 and Na2SO4 solutions. The effects of electrolytes concentration and applied potential were studied in the above two processes. Photocatalytic oxidation (PCO) was also performed in TiO2(P25) suspension under UV-irradiation for comparison. Enhanced decolorization performance...
