Magnesium diboride (MgB₂) has been explored as an alternative fuel to boron (B) due to its high energy density and the additive effect of magnesium (Mg) to promote B combustion. However, the primary oxidation of MgB₂ does not occur unless it decomposes at a high temperature (830 °C), which makes ignition difficult and the reaction slow. Recently, two-dimensional (2D) exfoliated MgB₂ nanosheets have attracted increasing attention due to their unique properties and potential applications in various fields. In this study, we investigate the potential of 2D exfoliated MgB₂ nanosheets as solid fuels for overcoming the challenges of MgB₂ combustion. We analyzed their oxidation behavior and energetic performance through material characterization and combustion tests under slow- and fast-heating conditions and compared their performance with those of bulk MgB₂, B nanoparticles, and a B/Mg nanoparticle mixture. This study highlights the potential of MgB₂ nanosheets as promising solid fuels with superior energetic properties.

作为固体燃料的剥离二硼化镁 (MgB2) 纳米片

二硼化镁（MgB2 _）由于其高能量密度以及镁（Mg）促进B燃烧的附加作用，已被探索作为硼（B）的替代燃料。_{然而，MgB 2}除非在高温（830℃）下分解，否则不会发生初级氧化，这使得点火困难且反应缓慢。近年来，二维（2D）剥离MgB ₂纳米片由于其独特的性能和在各个领域的潜在应用而引起了越来越多的关注。_{在这项研究中，我们研究了二维剥离 MgB 2纳米片作为固体燃料克服 MgB}₂燃烧挑战的潜力。我们通过材料表征和慢速和快速加热条件下的燃烧测试分析了它们的氧化行为和能量性能，并将它们的性能与块状 MgB ₂、B 纳米颗粒和 B/Mg 纳米颗粒混合物的性能进行了比较。_{这项研究强调了 MgB 2}纳米片作为具有优越能量特性的有前途的固体燃料的潜力。
