We report the transformation of gaseous ammonia to a liquid at room temperature and ambient pressure through mixing with simple solid ammonium salts. The resulting liquids, named eurefstics, are potentially advantageous for the storage and electrochemical conversion of ammonia and the realization of a green ammonia energy economy. Physical properties of these eurefstics, including the temperature-dependent composition and composition-dependent densities, are reported to glean initial insight into the formation and behavior of this intriguing liquid. Preliminary electrochemical investigations of the eurefstics were also performed. We have found that these eurefstics formed are conductive and can be used directly as electrolytes for ammonia electrolysis reactions to produce hydrogen on demand. Open-circuit potential measurements were also made to determine the formal potential of the hydrogen evolution and corresponding overpotentials. Finally, safety concerns of the eurefstics are discussed in comparison with other liquid phase energy carriers.

我们报告了通过与简单的固体铵盐混合，在室温和环境压力下将气态氨转化为液体。由此产生的液体，称为eurefstics，对于氨的储存和电化学转化以及实现绿色氨能源经济具有潜在的优势。据报道，这些 eurefstics 的物理特性，包括与温度相关的成分和与成分相关的密度，可以初步了解这种有趣液体的形成和行为。还对eurefstics进行了初步的电化学研究。我们发现，这些形成的eurefstics是导电的，可以直接用作氨电解反应的电解质，按需生产氢气。还进行了开路电位测量以确定析氢的形式电位和相应的过电位。最后，与其他液相能量载体相比，讨论了eurefstics的安全问题。
