| 摘 要： | 氧烛是一种使用方便、贮存容易、安全可靠的氧源。本文选用化学试剂Co2O3、Co3O4与自制催化剂CoOx作为氧烛药块分解的催化剂。通过性能试验得出,只有自制催化剂CoOx能使氧烛药块完全分解。并通过比表面积(BET)、透射电子显微镜(TEM)、X射线粉末衍射(XRD)和X光电子能谱(XPS)等手段对各催化剂的组成、物相和形貌及颗粒度的表征,分析了自制催化剂能有效降低氧烛药块分解温度的原因。

| Abstract: | The oxygen-generating candle is one kind of conveniently-used, easily-stored, safe and reliable oxygen source. Chemical reagents of Co2O3, Co3O4 and self-made catalyst CoOx were selected as catalysts of decomposition of oxygen candle pellet. Through the performance test, only self-made catalyst CoOx can cause the oxygen candle pellet to decompose completely. The constitution, phase, morphology and particle size of various catalysts were characterized by BET, transmission electron microscope (TEM), X-Ray diffraction (XRD) and X-Ray photoelectron spectyoscopy (XPS). The reason for the self-made catalyst to be able to reduce the oxygen candle pellet decomposition temperature effectively was analyzed. |
