摘要：

通过刷涂热分解法制备了锑掺杂的钛基二氧化锡(Ti/SnO2-Sb2O5)涂层电极. 在酸性介质中, 用扫描电镜(SEM)、X射线衍射仪(XRD)、循环伏安和快速寿命测试等方法研究了Ti/SnO2-Sb2O5电极制备条件、电极结构、性能和寿命. 结果表明, Ti/SnO2-Sb2O5电极涂层具有“干泥”结构, 用锡锑摩尔比为9:1的涂液组成、在550 ℃烧结温度下制备的Ti/SnO2-Sb2O5的电极涂层平整致密,龟裂小, 电极孔隙率小, 稳定性最好.

Abstract:

Antimony doped tin dioxide coated electrodes (Ti/SnO2-Sb2O5) on Ti substrates were prepared by the brush coating thermal decomposition method. Preparation conditions, structure, electrochemical characterization and service life of Ti/SnO2-Sb2O5 electrodes were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), cyclic voltammetry (CV) and accelerated life test methods. Results show that Ti/SnO2-Sb2O5 electrodes have a dry cracked-mud coating structure. A Ti/SnO2-Sb2O5 electrode coating prepared at an annealing temperature of 550 ℃ and with a molar ratio of nSn:nSb=9:1 for the precursor solution has a flat and compact surface, few cracks, low porosity, and good stability.
