The modified Ti/SnO₂-Sb-Mn/Re electrodes were prepared using rare earth (Re) Gd, Eu, Ce, and Er and various molar ratios of tin and manganese by thermal decomposition. To investigate the electrocatalytic performance of electrodes, phenol was applied as a model pollutant. Phenol removal pursued pseudofirst-order kinetics in the experimental range. The experimental outcomes show that the phenol degradation at ~95% and ~97% was found in Mn (1 mol%)/Re and Mn (2 mol%)/Re electrodes after treatment for 140 min. Accelerated lifetime testing showed that the best-accelerated service life could be measured only in Mn (3 mol%)/Re and Mn (4 mol%)/Re compared with other prepared Mn (0%,1%, and 2%)/Re electrodes under the condition of 500 mAcm^-2 current density in this study. The modified electrodes were then characterized, including oxygen evolution potential (OEP), crystal structure, and surface composition of the electrode coatings.

稀土掺杂Ti / SnO2-Sb-Mn电极的制备及其电催化性能

使用稀土（Re）Gd，Eu，Ce和Er以及各种摩尔比的锡和锰通过热分解制备了改性的Ti / SnO ₂ -Sb-Mn / Re电极。为了研究电极的电催化性能，使用苯酚作为模型污染物。苯酚的去除在实验范围内追求伪一级动力学。实验结果表明，处理140分钟后，在Mn（1 mol％）/ Re和Mn（2 mol％）/ Re电极中发现苯酚降解率为〜95％和〜97％。加速寿命测试表明，与其他制备的Mn（0％，1％和2％）/相比，仅以Mn（3 mol％）/ Re和Mn（4 mol％）/ Re可以测得的最佳加速寿命在500 mAcm ^-2的条件下重新焊接电极本研究中的电流密度。然后对改性电极进行表征，包括氧释放电势（OEP），晶体结构和电极涂层的表面组成。
