Abstract

Hydrogen storage technology based on ammonia carriers is a key part of the transition from fossil fuels to low-carbon energy sources. However, the high energy consumption and high carbon path dependency of the traditional ammonia industry are the core challenges constraining the development of current technologies. In this review, we focus on the core advantages of low-temperature plasma chemistry in ammonia synthesis, including mild conditions, environmental friendliness, flexibility, and controllability. We then propose a powerful approach for transitioning traditional ammonia synthesis technology in a sustainable direction. Firstly, we systematically sort out the time evolution of the plasma ammonia synthesis reactor and elucidate the mode of action of plasma-assisted ammonia synthesis. In particular, we provide an in-depth analysis of design optimization strategies for plasma catalysts to explore key catalytic mechanisms in ammonia synthesis systems. Finally, we evaluate the performance index of the existing plasma ammonia synthesis system and suggest feasible directions for future research to further improve the energy efficiency of the technology, promoting the development of the ammonia production process in a more sustainable and advanced direction.

非热等离子体氨合成的催化剂设计和机理研究。
基于氨载体的储氢技术是化石燃料向低碳能源转型的关键环节。然而,传统氨工业的高能耗和高碳路径依赖是制约当前技术发展的核心挑战。本文综述了低温等离子体化学在氨合成中的核心优势,包括条件温和、环境友好、灵活性和可控性。然后,我们提出了一种将传统合成氨技术向可持续方向转变的有力方法。首先,系统梳理了等离子体氨合成反应器的时间演化,阐明了等离子体辅助氨合成的作用方式。特别是,我们对等离子体催化剂的设计优化策略进行了深入分析,以探索氨合成系统中的关键催化机理。最后,对现有血浆氨合成系统的性能指标进行了评价,并提出了未来可行的研究方向,以进一步提高该技术的能效,促进氨生产工艺向更加可持续和先进的方向发展。
