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。 Oxygen candle is a kind of easy to use, easy storage, safe and reliable source of oxygen. In this paper, chemical reagents Co2O3, Co3O4 and self-made catalyst CoOx as a catalyst for the decomposition of oxygen candle block. Through the performance test, we found that only the self-made catalyst CoOx can completely decompose the oxygen candle mass. The catalysts were characterized by BET, TEM, XRD and XPS. Their phases, morphologies and particle sizes were characterized by X-ray powder diffraction (XRD) and X-ray photoelectron spectroscopy The self-made catalyst can effectively reduce the decomposition temperature of the oxy-candlesticks.
