为提高潜艇等密闭空间所使用的氧烛的体积储氧量，通过溶胶-凝胶法制备了Ni：Mn=6：1，3：1，2：1，1：1，1：2，1：3，1：6七种MnxNi（1-x）O催化剂，将其与LiClO4进行热重-差热分析（TG-DTA），通过对比空白样品和各混合样品的起始分解温度和最大分解速率温度，探究了MnxNi（1-x）O催化剂对LiClO4分解的催化性能。研究结果表明，MnxNi（1-x）O催化剂对LiClO4分解有很好的催化作用，起始分解温度降低128±13 ℃，其中Ni：Mn=1：6的催化性能最佳，起始分解温度为312 ℃，在372 ℃时的分解速率达到10.8%/min，分解温程最窄。
In order to improve Oxygen candles sealed space submarines used oxygen storage volume. Seven kinds of MnxNi(1-x)O catalysts were prepared by sol-gel method. The thermogravimetry-differential thermal analysis (TG-DTA) was carried out with LiClO4. The decomposition of LiClO4 by MnxNi(1-x)O catalysts were investigated by comparing the initial decomposition temperature and the maximum decomposition rate temperature of the blank sample and each mixed sample catalytic performance. The results show that the MnxNi(1-x)O catalyst has a good catalytic effect on the decomposition of LiClO4, and the initial decomposition temperature is reduced by 128±13℃. The catalytic performance of Ni:Mn=1:6 is the best, and the initial decomposition temperature is obtained. At 312℃, the decomposition rate at 372℃ reached 10.8%/min, and the decomposition temperature was the narrowest.
