Solid state ammonia synthesis using proton conductors has been shown to be a promising approach for nitroconversion of N2 to NH3. However, so far only materials have been used that conduct at temperatures above 400°C and the operation temperature needs to be reduced significantly. Therefore, the goal of this proposal is to use superprotonic solid acids to perform solid state ammonia synthesis at much lower temperatures than currently used. By combining the expertise on solid ionic transport, electrocatalysis and theoretical chemistry this proposal and consortium seeks a better fundamental understanding of how proton conductivity relates to nitroconversion and how nitroconversion can be further improved using solid state ammonia synthesis

使用质子导体的固相合成氨已被证明是氮气转化为氨的一种很有前途的方法。然而，到目前为止，只使用了在400°C以上导电的材料，需要显著降低操作温度。因此，这项提议的目标是使用超质子固体酸在比目前使用的温度低得多的温度下进行固态氨合成。通过结合固体离子传输、电催化和理论化学方面的专业知识，该提议和联盟寻求更好地从根本上理解质子传导性与硝化转化的关系，以及如何利用固态氨合成进一步提高硝化转化。
