Ti/TiO2纳米管阵列/PbO2-Pr电极制备及在电氧化有机废水中应用
Preparation of Ti/TiO2 Nanotube Arrays/PbO2-Pr Electrode and Its Application in Electrocatalytic Degradation of Organic Wastewater
摘要
Abstract
A novel Ti/TiO2 nanotube arrays(NTs)/PbO2-Pr electrode for the degradation of organic wastewater was fabricated by the pulse electrodeposition method.Pr-doped PbO2 nanoparticles were deposited on the TiO2 nanotube array substrate.Cyclic voltammetry(CV)and linear sweep voltammetry(LSV)were utilized to study the electrochemical performance of electrodes.The results demonstrate that Ti/TiO2 NTs/nanoPbO2-Pr electrodes(P)possess excellent electrocatalytic properties.The morphology,crystallinity and elemental composition of Ti/TiO2NTs/nanoPbO2-Pr electrodes were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS).The β-PbO2 nanoparticles are dispersed inside the TiO2 nanotubes and the doped Pr exists in the form of Pr2O3.The degradation of methylene blue was carried out to test electrocatalytic performance of this novel electrode.A 99.8％removal of methylene blue of Ti/TiO2NTs/nanoPbO2-Pr electrode within 120 min indicates its good activity.关键词
