Ethane 1,2-diamineborane (EDAB) is an alkyl-containing amine-borane adduct with improved hydrogen desorption properties as compared to ammonia borane. In this work, it is reported the high temperature thermolytic decomposition of EDAB. Thermolysis of EDAB has been investigated by concomitant thermogravimetry-differential thermal analysis-mass spectrometry experiments. EDAB shows up to four H₂ desorption events below 1000 °C. Small fractions of CH₄, C₂H₄ and CO/CO₂ are also observed at moderate-high temperatures. The solid-state thermolysis product has been characterized by means of different structural and chemical methods, such as X-ray diffraction, Raman spectroscopy, Scanning electron microscopy, Elemental analysis, and X-ray photoelectron spectroscopy (XPS). The obtained results indicate the formation of a ternary borocarbonitride compound with a poorly-crystalline graphitic-like structure. By contrast, XPS measurements show that the surface is rich in carbon and nitrogen oxides, which is quite different to the bulk of the material.
乙烷-1,2-二胺硼烷（EDAB）是一种含烷基的胺硼烷加合物，与氨硼烷相比，其氢解吸性能有所改善。在这项工作中，报道了EDAB的高温热解分解。通过同步热重-差示热分析-质谱实验研究了EDAB的热解。EDAB在1000℃以下显示出多达四次H₂解吸事件。在中高温下还观察到少量的CH₄、C₂H₄和CO/CO₂。通过不同的结构和化学方法对固态热解产物进行了表征，如X射线衍射、拉曼光谱、扫描电子显微镜、元素分析和X射线光电子能谱（XPS）。所得结果表明形成了具有弱结晶石墨状结构的三元硼碳氮化物化合物。相比之下，XPS测量表明表面富含碳和氮氧化物，这与材料本体有很大不同。
