Abstract
As the characterizations of electrode are meaningful for electric catalytic efficiency and mechanism, the improvement of electrode have raised considerable public concern in recent decades. However, the metal electrode have the drawbacks of high price and easy for toxicity, nano electrode restricted by difficulties for electrode coating, possibility of agglomeration, and abscission during reactions. Focus on those defects, the proposed study is going to establish a useful technique for polymer combined nano-electrode preparation. The morphology, functional groups, and other characterization of the Pt/TiO₂/graphene particles and organic composite nano Pt/TiO₂/graphene sheets were analyzed by transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), electrochemical impedance spectroscopy (EIS). To identify the stability of self-prepared electrodes, parameters such as catalysts dosage, current density and pH will be analyzed by using RBK5 as target pollutions. The results shows that after treatment for 50 min under optimized conditions (20 mA, 1 g/L NaCl), the degradation rate of acetaminophen almost reached 100%. After five times recycle, the self-prepared electrode could still maintained a high removal rate of 90%.
