不同掺杂元素的钛基PbO2电极对苯酚电催化氧化性能的影响
Effect of Ti/PbO2 Electrodes Doped with Different Elements on Electrocatalytic Oxidation Characteristics of Phenol
摘要
Abstract
Three types of electrodes, namely, Ti/PbO2, F-doped PbO2 (Ti/PbO2-F) and nano-Co3O4-doped Pb02(Ti/Pb02+Nano-CO3O4) electrodes, were prepared by electro-deposition method on the Ti substrate with the interlayer of SnO2-St2O5. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to study the compositions, structures and film morphologies of the electrodes. Electrocatalytic oxidation characteristics to phenol on the prepared electrodes were investigated by electrochemical method. The experimental results showed that compared with the Ti/PbO2 electrode, the potentials of oxygen evolution on the Ti/PbO2+F electrode apparently shifted more positively, while those of Ti/PbO2+Nano-Co3O4 electrode shifted negatively after the oxidation of phenol took place. This provided experimental evidence for the existence of some transient intermediates which underwent particularly fast reactions, i.e., the reaction of water molecule with phenol occurred before the dissociation of water molecule, which was more beneficial to the transformation and degradation of phenol.关键词
