Structure and Properties of CNT-PbO2 Anodes on Stainless Steel

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.
