The net electrode of (TiO2/Ti) loaded Cu2+ was prepared by micro-arc oxidation. Effect of the micro-arc oxidation electrolyte concentration, photoelectrocatalysis electrolyte concentration and initial photoelectric catalytic electrolysis spacing, applied voltage on the three-dimensional photoelectrocatalytic decolorization of methylene blue was investigated. The results show that photocatalytic effect of titanium mesh prepared by micro-arc oxidation in 6 g/L Na3PO4 solution for 5 min is the best, can reach to 25.3%; after titanium mesh electrode is modified by Cu2+ with micro-arc oxidation method under the conditions of 0.01 mol /L Cu2+ and 7 min micro-arc oxidation time, methylene blue decolorization rate of the three-dimensional photoelectric catalytic system can reach to 46.2% when methylene blue is 5 mg/L, sodium sulfate solution is 0.01 mol/L, electrolytic distance is 1.5 cm, applied voltage is 3 V and pH is 5.
