【摘要】 采用热刷涂层法制备了钛载SnO₂-Sb中间层,通过电沉积法得到Nd-碳纳米管（CNTs）-PbO₂/SnO₂-Sb/Ti电极。利用扫描电子显微镜（SEM）、X射线衍射（XRD）、X射线光电子能谱（XPS）对电极的组成、形貌进行了表征,采用接触角分析和电化学方法考察了电极的电化学性能。结果表明,稀土金属掺杂于SnO₂-Sb/Ti中间层可阻隔氧和基体的接触而有效保护钛基,提高电极材料的稳定性、析氧电位和电化学降解苯酚的能力。另外,Nd-CNTs-PbO₂/SnO₂-Sb/Ti可增加阳极材料的憎水性,有利于提高电极的电化学降解效率。更多还原

【Abstract】 The Nd-carbon nanotubes（CNTs）-PbO₂/SnO₂-Sb/Ti electrode was prepared by an electrolytic deposition technique based on hot brush coating method.The surface morphologies and composition of electrodes were examined by SEM,XRD and XPS analysis.The electrochemical performances of Nd-CNTs-PbO₂/SnO₂-Sb/Ti were studied using contact angle meter and electrochemical method.The rare earth metal doped SnO₂-Sb/Ti obstructed the contagion between oxygen and Ti substrate,which would be beneficial to the improvement of electrode stability,oxygen evolution potential and electrochemical degradation of phenol.Moreover,the electrochemical degradation efficiency of Nd-CNTs-PbO₂/SnO₂-Sb/Ti was significantly improved due to the enhancement of hydrophobicity.更多还原
