Differently Prepared PbO2/Graphitic Carbon Nitride Composites for Efficient Electrochemical Removal of Reactive Black 5 Dye

In this paper, electrochemical degradation of Reactive Black 5 (RB5) textile azo dye was examined in regard to different synthesis procedures for making PbO2–graphitic carbon nitride (g-C3N4) electrode. The reaction PbOH3- with ClO− the presence surfactants, i.e., cetyltrimethylammonium bromide (CTAB) and tetrabutylammonium phosphate (TBAP), under conventional conditions, resulted formation PbO2 varying morphology. obtained materials were combined g-C3N4 preparation final composite materials, which then characterized morphologically electrochemically. After optimizing method, it shown that an anode comprising a steel electrode coated synthesized using CTAB as template g-C3N4, 0.15 M Na2SO4 supporting electrolyte, gave best performance RB5 removal from 35 mg/L solution. treatment duration 60 min, applying current 0.17 A (electrode surface 4 cm2, density 42.5 mA/cm2), while initial pH testing solution 2. reusability longevity (which showed no significant change activity throughout study) may suggest approach is promising candidate wastewater pollutant removal.
