    摘要:

    通過熱分解法制備了含IrO2-MnO2中間層Ti/RuO2-TiO2-SnO2電極，采用SEM、EDX、XRD、CV等檢測(cè)方法對(duì)中間層進(jìn)行表征，同時(shí)采用強(qiáng)化加速壽命試驗(yàn)對(duì)電極電化學(xué)穩(wěn)定性進(jìn)行表征。結(jié)果表明：450 ℃時(shí)前軀體完全氧化并形成固溶體，制備的中間層晶粒細(xì)小，表面結(jié)構(gòu)致密，電化學(xué)孔隙率小。添加中間層使Ti/RuO2-TiO2-SnO2電極強(qiáng)化壽命由未加中間層的7.5 h提高到995.8 h，遠(yuǎn)高于國家標(biāo)準(zhǔn)20 h。

    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.
