| 摘 要： | 通过热分解法制备了含IrO2-MnO2中间层Ti/RuO2-TiO2-SnO2电极,采用SEM、EDX、XRD、CV等检测方法对中间层进行表征,同时采用强化加速寿命试验对电极电化学稳定性进行表征。结果表明:450℃时前躯体完全氧化并形成固溶体,制备的中间层晶粒细小,表面结构致密,电化学孔隙率小。添加中间层使Ti/RuO2-TiO2-SnO2电极强化寿命由未加中间层的7.5h提高到995.8h,远高于国家标准20h。

| Abstract: | Ti/RuO2-TiO2-SnO2 electrode with IrO2-MnO2 interlayer was prepared via thermal decomposition. SEM, EDX, XRD and CV were employed to characterize the interlayer, and electrochemical stability was characterized by acceleration life time test. Results show that precursors are completed decomposed at 450 oC. The interlay shows fine grains, compact surface structure and low electrochemical porosity. Acceleration life time is greatly increased form 7.5 h to 995.8 h by adding interlay, much higher than the national standard of 20 h. |
