Ammonia is a zero-carbon molecule and a promising hydrogen storage material with an increasing global demand. The synthesis of ammonia still relies on the traditional Haber–Bosch method, which has high ammonia production but strict reaction conditions and high energy consumption. It is critical to develop an efficient green ammonia synthesis process. It is presented that shifting or breaking the scaling relationship between the adsorption energy and activation energy of nitrogen over transition metals in traditional catalytic methods can result in a high ammonia production efficiency under mild conditions. This work reviews the current progress in various catalytic ammonia synthesis methods based on the approach of avoiding the scaling relationship. The green plasma ammonia processes focused on N₂ and H₂/H₂O are emphasized in detail, such as plasma-coupled catalysis, plasma-coupled electrocatalysis, plasma-coupled photocatalysis, and plasma-coupled chemical looping due to the N₂ activated in plasma. These novel systems are designed to overcome the limitations of a single ammonia synthesis system and are expected to achieve green and sustainable ammonia production.

用非热等离子体方法避免氨合成中的结垢关系的策略——“转移”或“中断”方法

氨是一种零碳分子，也是一种有前景的储氢材料，全球需求不断增长。氨的合成仍依赖传统的Haber-Bosch法，该法氨产量高，但反应条件严格，能耗高。开发高效的绿色氨合成工艺至关重要。研究表明，改变或打破传统催化方法中氮在过渡金属上的吸附能和活化能之间的比例关系可以在温和的条件下获得高的氨生产效率。本文综述了基于避免结垢关系的各种催化氨合成方法的当前进展。_{详细强调了以N 2}和H ₂ /H ₂ O为重点的绿色等离子体氨工艺，例如等离子体耦合催化、等离子体耦合电催化、等离子体耦合光催化以及由于N ₂活化而产生的等离子体耦合化学循环。在血浆中。这些新颖的系统旨在克服单一氨合成系统的局限性，有望实现绿色、可持续的氨生产。
