聚合氮(PN)由于具有Lewis碱性质，是一种潜在的绿色催化材料，由于其可观的储能能力和对环境友好的分解产物氮气，是一种高能量密度材料(HEDM)。大多数研究都集中在理论研究上，提出了各种结构，但也进行了一些成功的实验。等离子体技术作为一种可行的材料合成技术，可能为聚合物氮的合成提供新的可能性。本文综述了聚合氮的研究现状、等离子体技术及其在聚合氮合成中的潜在催化应用。传统的热法合成聚合氮需要极高的温度和高压，热力学不稳定，而一些PNS表现出良好的催化活性。高压、阳离子和底物是聚合物氮合成和稳定的重要因素。等离子体过程充满了高能活性粒子，可以在温和的条件下运行，非常适合温度敏感材料。因此，等离子体在聚合物氮合成中具有广阔的应用前景。为了增加产品，适当的前体和底物是重要的，这是进一步开发聚合氮所必需的。随着对等离子体处理机理的深入了解，它将会有更广泛的应用。
Polymeric nitrogen (PN) is potentially a green catalytic material due to its Lewis base property, and a high-energy density material (HEDM) due to its considerable energy storage and the environment-friendly decomposition product, nitrogen gas. Most research has focused on theoretical studies and various structures were proposed, while a few successful experiments were carried out. Plasma technology, as a viable synthesis technique for materials, may provide new possibilities for polymeric nitrogen. In this review, the polymeric nitrogen study, the plasma technology, and its potential catalytic applications for polymeric nitrogen synthesis are reviewed and summarized. Polymeric nitrogen synthesis requires extremely high temperature and high pressure with traditional thermal method and is thermodynamically unstable, while some PNs exhibit excellent catalytic activity. High pressure, cations and substrates are important for polymeric nitrogen synthesis and stabilization. Plasma processes, full of energetically active particles, can operate under mild conditions and is very good for temperature-sensitive materials. Thus, plasma has a promising potential application for polymeric nitrogen synthesis. Proper precursors and substrates are important in order to increase products, which are necessary for further exploitation of polymeric nitrogen. With better understanding of the mechanism of plasma treatment, it will have wider applications.
