To improve the service life of SnO₂−Sb electrodes in degradation of refractory wastewater, we report anodic information of tin oxide antimony on top of Nb−TiO₂ nanotubes (Nb−Ti/Nb−TiO₂−NTs/ATONPs) prepared through screen‐printing. It was found that the Nb−Ti/Nb−TiO₂−NTs/ATONPs anodes presented a significantly enhanced in electro‐catalytic oxidation performance (in Acid Red 73) compared to titanium‐based tin antimony electrodes (Ti/ATONPs). Additionally, the electrochemical properties and the stability were further studied by the electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV), cyclic voltammetry (CV), chronoamperometry (CA) measurements and accelerated life test, respectively. These results indicated that Nb−TiO₂−NTs/ATONPs anode possessed Nb−TiO₂ nanotubes which exhibited a higher oxygen evolution potential (2.24 V vs. Ag/AgCl), as well as a better wettability, a larger current at constant potential and 2.1 times longer lifetime than the conventional Ti/ATONPs anode.

锑掺杂的氧化锡纳米颗粒沉积在Nb-TiO2纳米管上用于电化学降解生物耐火材料

为了提高SnO ₂ -Sb电极在难降解废水降解中的使用寿命，我们报道了通过筛网制备的Nb-TiO ₂纳米管（Nb-Ti / Nb-TiO ₂ -NTs / ATONPs）上氧化锡锑的阳极信息。打印。发现Nb-Ti / Nb-TiO ₂与钛基锡锑电极（Ti / ATONPs）相比，-NTs / ATONPs阳极的电催化氧化性能（在酸性红73中）显着提高。此外，分别通过电化学阻抗谱（EIS），线性扫描伏安法（LSV），循环伏安法（CV），计时安培法（CA）和加速寿命试验进一步研究了电化学性能和稳定性。这些结果表明，Nb-TiO ₂ -NTs / ATONPs阳极具有Nb-TiO ₂纳米管，该纳米管具有较高的析氧电势（2.24 V vs. Ag / AgCl），并且具有更好的润湿性，在恒定电势下具有更大的电流和寿命是传统Ti / ATONP阳极的2.1倍。
