用热分析技术研究ＮｉＣｏ２Ｏ４尖晶石型催化剂的还原特性，考察了助剂Ｋ＋、Ａｌ３＋的加入对ＮｉＣｏ２Ｏ４尖晶石型催化剂氧活性的影响。结果表明：Ｋ＋的加入使还原温度明显降低，有助于促进催化剂的氧活性，而Ａｌ３＋的加入起抑制作用。
The thermal properties of NiCo2O4 spinel catalysts were investigated by means of thermal analysis. The effect of additives K +, Al3 + on the oxygen activity of NiCo2O4 spinel catalysts was investigated. The results showed that the addition of K + significantly reduced the reduction temperature, which promoted the oxygen activity of the catalyst. However, the addition of Al3 + had an inhibitory effect.
