| 中文摘要: |
| 采用涂层热解法在 Ti 基体表面制备不同掺杂量的铕掺杂锡锑中间层,并在锡锑中间层的表面电镀上 PbO2。 对所制备的电极作 LSV 曲线,研究了电极的电化学性能;以对硝基苯酚为目标有机物,考察了电极的电催化活性;采用 SEM,XRD 等分析方法表征了电极中间层的形态、元素组成和结构组成,据此分析了电极的性质。 结果表明,铕掺杂量对电极的各项性能有较大影响,制备电极时以 n ( Sn ) : n ( Sb ) : n ( Eu ) = 1 : 0 . 1 : 0 . 01为佳,该掺杂量下得到的电极析氧电位和电催化能力较高,表面涂层结构和覆盖度较好,电化学寿命达 78 . 6 h。 |
| 英文摘要: |
| Eu doped intermediate layer of SnO2-Sb with different doping amount were prepared by the thermal decomposition method. The PbO2was electroplated on the interme diate layer of SnO2-Sb. The electrochemical performance of the prepared electrodes was evaluated with linear sweep voltammetry( LSV) ; The degradation ability of the prepared electrodes was investigated using p-nitrophenol as a model pollutant; The micrograph, the element composition and the structure of the intermediate layer were analyzed by SEM and XRD, thus the properties of the electrodes were investigate. The results show that, the Eu doping amount has more effect on various performance of electrode. The optimal doping amount is n( Sn) : n( Sb) : n( Eu) = 1 :0 . 1 : 0 . 01 . The electrode at this doping amount has higher oxygen evolution potential and electrocatalysis ability, and better coverage and structure of the electrode. The eletrochemical life of the electrodes achives up to 78 . 6 h. |
