Ammonia plays a crucial role in industry and agriculture worldwide, but traditional industrial ammonia production methods are energy-intensive and negatively impact the environment. Ammonia synthesis using low-temperature plasma technology has gained traction in the pursuit of environment-benign and cost-effective methods for producing green ammonia. This Review discusses the recent advances in low-temperature plasma-assisted ammonia synthesis, focusing on three main routes: N+H plasma-only, N+HO plasma-only, and plasma coupled with other technologies. The reaction pathways involved in the plasma-assisted ammonia synthesis, as well as the process parameters, including the optimum catalyst types and discharge schemes, are examined. Building upon the current research status, the challenges and research opportunities in the plasma-assisted ammonia synthesis processes are outlined. The article concludes with the outlook for the future development of the plasma-assisted ammonia synthesis technology in real-life industrial applications.
氨在全球工农业中发挥着至关重要的作用，但传统的工业氨生产方法能源密集且对环境有负面影响。利用低温等离子体技术合成氨在寻求环境友好且经济高效的绿色氨生产方法方面受到了关注。本综述讨论了低温等离子体辅助氨合成的最新进展，重点关注三条主要途径：仅N + H等离子体、仅N + HO等离子体以及等离子体与其他技术耦合。研究了等离子体辅助氨合成所涉及的反应途径以及工艺参数，包括最佳催化剂类型和放电方案。基于当前的研究现状，概述了等离子体辅助氨合成过程中的挑战和研究机遇。文章最后展望了等离子体辅助氨合成技术在实际工业应用中的未来发展前景。
