Structure and Properties of CNT-PbO2 Anodes on Stainless Steel

Article Preview

Abstract:

An ideal anodes used for the electrochemical oxidation of organic wastewater should have excellent activity, stability and high oxygen evolution potential. In this paper the CNT (Carbon Nanotubes)-PbO2 films electrodeposited on stainless steel were prepared. X-ray diffraction (XRD) patterns and SEM images indicated that CNT particles and PbO2 were able to achieve co-deposit and the composite CNT-PbO2 films were compact. The cyclic voltammograms of the CNT-PbO2 films studied in 0.5M H2SO4 at a scan rate of 100 mV/s showed that the CNT-PbO2 film has high electrochemical stability. The results of wastewater treatment indicated that the CNT-PbO2 anodes have excellent activity in ammonia wastewater treatment.
