摘要
通过化学共沉淀法制备了钛酸镍铝掺杂催化剂,利用X射线衍射光谱法(XRD)和扫描电子显微镜法(SEM)对制备的钛酸镍铝掺杂催化剂进行检测,同时采用阴极极化曲线、恒电位放电和恒电流放电等电化学测试手段来验证,研究该催化剂在碱性电解液NaOH中的催化性能。结果表明,化学共沉淀法制备的钛酸镍铝掺杂催化剂(NixAl1-xTiO3)为钙钛矿型结构。NixAl1-xTiO3催化剂在碱性介质6mol/L NaOH中具有较好的电催化活性,在锌-空气电池中可进行大电流放电。
The nickel aluminum titanate doped catalysts were prepared by chemical co-precipitation, the use of X-ray diffraction spectroscopy（XRD） and scanning electron microscopy（SEM） on the preparation of nickel aluminum titanate doped catalysts were detected, while cathodic polarization curves, potentiostatic and galvanostatic discharge electrochemical means to verify the catalyst in the alkaline electrolyte of NaOH in the catalytic performance. The results show that the chemical coprecipitation of nickel aluminum titanate doped catalysts （NixAl1-xTiO3） perovskitetype structure. NixAl1-xTiO3 in alkaline medium of 6mol/L NaOH catalyst has a good electrocatalytic activity in the zinc-air battery and can be large current discharge.
