The synthesis of Mg3N2, a new safe ammonia carrier, by the nitridation of MgO using a simple plasma process is proposed and demonstrated. Recently, ammonia has been considered a promising energy storage material because of its high hydrogen storage density. However, the toxicity of ammonia is an essential safety concern in the storage and transport sector. Hence, a safety ammonia carrier is required for the dissemination of ammonia as an energy carrier. Therefore, in this study, we focus on Mg3N2 synthesis by the nitridation of MgO using an atmospheric pressure nonthermal plasma in a mixed gas atmosphere of N2 and H2. At present, 0.3% of MgO nitridation was achieved within 40 min of plasma synthesis. If complete nitridation of MgO becomes possible in the future, a breakthrough will occur in the field of energy storage materials.

大气压非热等离子体合成作为安全氨载体的氮化镁

提出并演示了通过使用简单的等离子体工艺氮化 MgO 来合成 Mg3N2，一种新的安全氨载体。近年来，氨因其高储氢密度而被认为是一种很有前途的储能材料。然而，氨的毒性是储存和运输部门的基本安全问题。因此，氨作为能量载体的传播需要安全的氨载体。因此，在本研究中，我们专注于在 N2 和 H2 的混合气体气氛中使用常压非热等离子体通过 MgO 氮化来合成 Mg3N2。目前，在等离子体合成的 40 分钟内实现了 0.3% 的 MgO 氮化。如果未来MgO的完全氮化成为可能，储能材料领域将出现突破。
