针对目前低浓度氯化钠电解过程中存在的氧化物尺寸稳定阳极(DSA)使用寿命短以及Pt电极使用量高的问题,本研究通过磁控溅射法制备了具有沿[111]方向择优生长的Pt/Ti电极。SEM结果显示,磁控Pt表面平整,分散均匀,粒度大小为10 nm;通过XPS表征,未见到基体Ti的特征峰,说明其表面覆盖度好。电化学循环伏安曲线(CV)显示,磁控Pt的电化学面积最小,仅为1.08 cm~2,接近电极表观面积;磁控Pt氧区吸附电量和氢区吸附电量的比仅为0.83,说明其对氧吸附能力较差,不利于发生析氧反应。在单位电化学面积上,当电极电势为1.6 V时,磁控Pt的析氯电流达到0.085 A/cm~2,分别是电沉积Pt和热分解Pt的3.27和49.0倍,说明磁控P...

To solve the short service life of dimensionally stable anode (DSA) and the high dosage of Pt electrode in the process of low concentration sodium chloride electrolysis, the Pt/Ti electrode preferred growth along the [111] direction was prepared by magnetron sputtering. The electrode surface of the magnetron sputtering Pt was uniform with particle size of 10 nm. The characteristic peaks of Ti were not found in the XPS spectrum, which showed that the Ti matrix was completely covered by Pt. Electrochemical cyclic voltammetry (CV) results showed that the electrochemical area of the magnetron sput...
