Electrochemical Degradation of Benzene in Water Using Platinum Supported on Carbon Black Materials

Abstract:

This study investigated the feasibility of the electrochemical degradation of benzene (C₆H₆) in a NaCl electrolyte solution between 0.05 and 0.5 M under the temperature of 298 K and reaction concentration between 1.28×10^-5 and 1.28×10^-3 M with an applied potential of 3 V was conducted in this study to investigate the destruction of the C₆H₆ in the batch reactors using a Pt/XC-72 composite as a catalyst. Experimental results indicated that the optimal conditions in the reaction were developed as a NaCl solution with 0.1 M at pH of 1.0 under C₆H₆ concentration of 6.41×10^-4 M. The results reveal that electrochemical degradation of C₆H₆ in acidic medium is highly effective, while a maximum about 41% reduction at 120 min was achieved with Pt/XC-72 composite during the electrochemical degradation. In comparsion, the removal efficiency reached only 29% with the Pt electrode, showing the suitability of the Pt/XC-72 composites for electro-oxidation of C₆H₆. As a result, XC-72 carbon black materials played an important role in the decomposition of C₆H₆. Furthermore, the Pt/XC-72 composite used in this research has been developed as a potential catalyst for the application of C₆H₆ electro-oxidation.
