在非氯盐体系下,采用化学共沉淀法制备纳米级锑掺杂二氧化锡（ATO）粉体材料,分析锑掺杂浓度、前驱体pH值和前驱体煅烧温度对电导率的影响;采用优化的Adams法,以纳米ATO粉体为载体,制备担载型析氧催化剂二氧化锒（IrO2）/ATO,并进行XRD分析、电化学阻抗及极化曲线测试。制备ATO粉体电导率最大时（0.581 S/cm）的条件为：Sb掺杂浓度10%,pH值为3.5,煅烧温度为600℃。采用IrO2/ATO催化剂的单体电池,在800mA/cm＾2、80℃时,所需槽电压仅为1.40V。

英文摘要：

Nano antimony-doped tin oxide（ATO） powder was prepared with chemical co-precipitation method in the system without chlorine salt. The effect on the conductivity of prepared ATO powder with different amount of antimony doped, pH of the precursor and the calcination temperature of the precursor was investigated. Catalyst for oxygen evolution using the nano ATO powder as support was prepared by the optimized Adams method and was characterized by XRD, EIS and polarization curve test. The highest conductivity of ATO powder was obtained with 0. 581 S/cm when the condition was： Sb doping amount of 10% , pH value of 3.5, calcination temperature of 600 ℃. Due to fine dispersion of active phase on the ATO support with fine electrical conductivity, the mass activity of the prepared catalyst was increased. A cell performance of 800 mA/cm^2 at 1.40 V was achieved at 80 ℃.
