【摘要】：將Ti N納米粉體與Ta Cl5正丁醇飽和溶液混合制得中間層涂覆液,通過熱分解法在不同焙燒溫度下得到了含有中間層的Ti/(Ti-Tax)O2/Ir O2電極,并與相同工藝下得到的傳統(tǒng)Ti/Ir O2電極進(jìn)行對比分析.采用X射線衍射和掃描電子顯微鏡對制備的電極進(jìn)行了表征,通過循環(huán)伏安曲線、極化曲線和恒流加速壽命測試等電化學(xué)手段對電極性能進(jìn)行了分析.結(jié)果表明,引入中間層可以使Ti/(Ti-Tax)O2/Ir O2電極400℃低溫焙燒樣品表層Ir O2結(jié)晶發(fā)育更好,得到了通常高溫下才具有的典型龜裂紋形貌;相對于500℃高溫焙燒樣品,其在海水中的電化學(xué)活性表面積提高近6倍,在4℃和100 m A/cm2電流密度下的電極電位(1.37 V)降低100 m V,催化性能得到顯著提高;同時(shí)加速壽命相對于傳統(tǒng)的Ti/Ir O2電極提高10倍以上,是一種適用于低溫海水環(huán)境的、具有較高活性和耐久性的新型陽極.
[Abstract]:The intermediate layer coating solution was prepared by mixing the nano tin powder with the saturated solution of Ta Cl5 n-butanol. The Ti/(Ti-Tax)O2/Ir O 2 electrode containing the intermediate layer was obtained by thermal decomposition at different calcination temperatures. And compared with the traditional Ti/Ir O 2 electrode obtained by the same process. The electrode was characterized by X-ray diffraction and scanning electron microscope. The electrochemical properties of the electrode were analyzed by cyclic voltammetry, polarization curve and constant current accelerated life test. The results show that the crystallization of ir O 2 in the surface layer of Ti/(Ti-Tax)O2/Ir O 2 electrode calcined at 400 鈩，
